To the handful of observers gathered at the edge of the field, the craft must have looked like something out of science fiction, with its gleaming barrel-shaped fuselage, gaping nose intake, and stubby wings awkwardly mounted high atop its fuselage. More baffling still, it lacked the one feature every aircraft was supposed to have: a propeller. When test pilot Erich Warsitz climbed into the cockpit and started the engine, the air filled not with the familiar drone <\/span><\/span><\/span><span style=\"font-size: small;\">of reciprocating<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> pistons but an unearthly, high-pitched screech. Then, as if propelled by magic, the aircraft lurched forward and trundled down the runway before leaping into the air. For the next six minutes, <\/span><\/span><\/span><span style=\"font-size: small;\">Warsitz circled<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> the airfield, reaching a maximum speed of 598 kilometres an hour, before touching back down on the runway. In that moment, aviation history changed forever as the Heinkel He-178 became the first aircraft to fly under jet power. Within two decades, piston-powered aircraft would become all but obsolete in commercial and military aircraft; the jet age had begun. But who invented this now-ubiquitous form of aircraft propulsion, and how did it come to rule the skies? Well, light up your afterburners and <\/span><\/span><\/span><span style=\"font-size: small;\">let\u2019s <\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">dive into the danger zone, <\/span><\/span><\/span><span style=\"font-size: small;\">exploring<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> t<\/span><\/span><\/span><span style=\"font-size: small;\">he <\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">fascinating history of the jet engine.<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">By the end of the 1930s, it was becoming clear that conventional reciprocating engine and propeller technology had been pushed to its limits. On April 26, 1939, German test pilot Fritz Wendel set a world airspeed record for piston-powered aircraft when he flew the Messerschmitt Me 209 V1 prototype fighter to a blistering 755 kilometres per hour (about 470 mph). This record would not be broken until 1969 &#8211; and then only by 25 kilometres per hour. At higher speeds, propeller blades begin to travel supersonically, forming shockwaves that reduce their efficiency and prevent aircraft from flying any faster. One solution to this problem is to fly at higher altitudes, where there is less air resistance. However, at these altitudes propellers must spin faster to generate sufficient thrust, and the thinner air starves piston engines of oxygen and thus power. Of course, these are partially solvable problems. For example, <\/span><\/span><\/span><span style=\"font-size: small;\">m<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">ore thrust can be generated through the use of specially-designed supersonic propellers, but even then the speed record for propeller-driven aircraft is 925 kilometres per hour (57<\/span><\/span><\/span><span style=\"font-size: small;\">5<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> mph), set by the Russian Tupolev Tu-95 strategic bomber. Thus, for aircraft to fly any faster in a practical way, an entirely new kind of propulsion system was needed. Enter the jet engine. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">As previously covered in our video <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Was the First Jet Plane Really Flown in 1910? <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">on our sister aviation channel <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Higher Learning, <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">the idea of propelling an aircraft using a jet of air instead of a spinning propeller is nearly as old as aviation itself. As early as 1910, Romanian inventor and aerodynamicist Henri Coanda claimed to have built and briefly flown an innovative biplane powered by what he called a \u201cturbo-propulsor\u201d, which unfortunately caught fire and crashed on its maiden flight. While Coanda\u2019s claims are disputed, what is known is that his \u201cturbo-propulsor\u201d was not a jet engine as we would recognize it today. Rather, it was a form of <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>motorjet, <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">in which a conventional piston engine drives a turbine to generate a high-speed air jet. In certain motorjet designs, fuel is injected into the jet and ignited to produce extra thrust, as in a modern afterburner. The first verified motorjet powered aircraft to take to the skies was the Italian Caproni-Campini N.1, which made its maiden flight on August 27, 1940. Yet despite its innovative power plant, the N.1 was unable to outperform conventional propeller-powered aircraft of the era and suffered from unacceptably high fuel consumption and overheating. And while the Soviet Union also briefly experimented with motorjet-powered fighters like the Mikoyan-Guerevich I-250 and Sukhoi Su-5, it soon became clear that motorjets were a technological dead end, and these unusual powerplants soon became little more than a footnote in the history of aircraft propulsion.<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">A true jet engine or <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>turbojet<\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> is, in principle at least, remarkably simple, consisting of four basic components: a <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>compressor<\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">, a <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>combustion chamber,<\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> a <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>turbine,<\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> and a <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>nozzle. <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Air enters at the front of the engine, where it is compressed by the compressor before being fed into the combustion chamber. Here, the air is mixed with fuel and ignited, creating hot, high-pressure exhaust. This exhaust is then passed through the turbine before being expelled out the nozzle at the rear of the engine, generating forward thrust. Meanwhile, the turbine extracts a small amount of energy from the exhaust and uses it, via a connecting shaft, to drive the compressor, making the whole cycle self-sustaining. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">The first modern gas turbine was patented in 1791 by English inventor John Barber, who planned to use it to propel a \u201chorseless carriage.\u201d Similar devices were created in 1872 by Dr. F. Stolze and 1903 by Aegidius Elling, the latter of which became the first successful self-sustaining gas turbine. In 1918, Dr. Stanford A. Moss of American firm General Electric invented a two-stage turbine called the <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>turbosupercharger <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">or simply <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>turbocharger, <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">though this was not intended for powering vehicles directly. Rather, the turbocharger used waste energy from a conventional piston engine\u2019s exhaust to feed more air into the engine\u2019s intake manifold, increasing its power input. Two decades later, this innovation would prove vital to the Allied strategic bombing campaigns over Western Europe and Japan. However, none of these early gas turbines were suited to use in aviation; for the technology to become a truly viable form of propulsion, a number of difficult technical problems first had to be overcome, such as finding materials heat-resistant enough to prevent the turbine blades from distorting or the combustion chamber from burning through while simultaneously being lightweight enough to mount in an aircraft.<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">As we have covered many times on this channel, few truly groundbreaking innovations are the product of a single brilliant mind. Rather, they are developed over many years of even decades by dozens of hardworking &#8211; and often overlooked &#8211; individuals. But while the jet engine is no exception, it would likely not have been developed or adopted as early as it was were it not for the contributions of two key figures, who both came up with the idea at around the same time and unwittingly found themselves in a high-stakes race to get their groundbreaking inventions into the air. These extraordinary men were Sir Frank Whittle and Hans von Ohain.<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Frank Whittle was born on June 1, 1907 in Coventry, England, the eldest son of mechanic Moses Whittle and his wife Sarah Garlick. Fascinated by machines from an early age, Whittle learned about practical engineering by helping out in his father\u2019s workshop, and in 1923 at the age of 16 signed up to join the Royal Air Force as an Aircraft Apprentice. Unfortunately, he was rejected when his short height and slight build caused him to fail his medical examination. Determined to join up, he embarked on a regimen of intense physical exercise to bulk himself up and applied twice more &#8211; once under an assumed name &#8211; before finally being accepted. He was then sent to No.1 Squadron of No.4 Apprentices Wing at RAF Cranwell for a three-year course in aircraft maintenance. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">To Whittle\u2019s dismay, he soon discovered that strict RAF discipline was not to his liking, and that his physical limitations made his becoming a pilot an unlikely prospect. He grew so depressed that he seriously considered deserting, only keeping up his spirits by joining the Model Aircraft Society. Then, in 1926, the quality of Whittle\u2019s models so impressed the commander of the Apprentice Wing that he recommended him for officer training at RAF College Cranwell. Here, Whittle finally got the chance to take flight training, soloing in 1927 after only 13.5 hours of instruction. He soon became an accomplished pilot, gaining a reputation for daring stunt flying. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">As part of his officer course, Whittle was required to prepare a thesis, which he decided to write on future developments in aircraft technology. Whittle <\/span><\/span><\/span><span style=\"font-size: small;\">calculated<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> that an aircraft could achieve maximum range by flying at high altitudes, where reduced air density results in less drag. However, the physics of propellers and piston engines meant that at such altitudes, the aircraft\u2019s performance would also be reduced. It was while pondering this problem in 1929 <\/span><\/span><\/span><span style=\"font-size: small;\">that<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> Whittle had an epiphany: why not replace the piston engine and propeller with a gas turbine, which could theoretically produce far greater thrust at higher altitudes? Whittle obtained a patent for his engine design in 1930 at the age of only 22, and his superiors at RAF Cranwell were sufficiently impressed that they arranged for him to present his idea to the Air Ministry. However, as Whittle later recalled:<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\">\u201c<span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>The result was extremely disappointing. The net outcome was a letter from the Ministry to the effect that any form of gas turbine was \u2018impracticable\u2019.\u201d<\/i><\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Indeed, the Air Ministry was so <\/span><\/span><\/span><span style=\"font-size: small;\">uninterested in Whittle&#8217;s<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> idea that they allowed his patent to be openly published. As a result, his design soon became known to engineers across Europe &#8211; including, fatefully, in Germany. Nonetheless, Whittle continued to develop the design on his own time, though he had so little money that when his patent expired in 1935, he was unable to renew it. But Whittle was not entirely without friends, and in that same year some fellow RAF officers arranged a meeting between Whittle and Lancelot Whyte of the banking firm O.T. Falk and Partners. As Whyte later recalled:<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\">\u201c<span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>The impression he made was overwhelming,\u201d Whyte recalls. I have never been so quickly convinced, or so happy to find one\u2019s highest standards met. . . . This was genius, not talent\u2026.Whittle expressed his idea with superb conciseness: \u2018Reciprocating engines are exhausted. They have hundreds of parts jerking to and fro, and they cannot be made more powerful without becoming too complicated. The engine of the future must produce 2,000 hp with one moving part: a spinning turbine and compressor.\u2019\u201d<\/i><\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Whyte immediately agreed to fund the establishment of a small experimental engine company, dubbed Power Jets Ltd. While the RAF still considered the turbojet impractical for military use, they nonetheless allowed Whittle to pursue the venture provided he <\/span><\/span><\/span><span style=\"font-size: small;\">spent<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> no more than six hours a week on it &#8211; an order he flagrantly ignored.<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Whittle and his assistants set up shop in the workshops of the British Thomson-Houston Company, who manufactured the components for Whittle\u2019s first experimental test engine &#8211; dubbed the Whittle Unit or WU. Very much a proof of concept, the WU used a single-stage centrifugal compressor connected to a single combustion chamber and single-stage turbine, the whole assembly being housed in a sheet metal enclosure to catch turbine blades and other components should they fly off the engine. After two years of work, the WU was finally ready for its first test run on April 12, 1937. Whittle later described the event:<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\">\u201c<span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Immediately, with a rising scream, the engine began to accelerate out of control. I promptly shut the valve, but the uncontrolled acceleration continued. Everyone around took to their heels except me. I was paralyzed with fright and remained rooted to the spot.\u201d<\/i><\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">A few seconds later, however, the engine decelerated and came back under control. The problem, it was discovered, was a puddle of fuel which had gathered in the combustion chamber during a previous fuel pump test. Whittle installed a drain at the bottom of the chamber and tried again the following day, though this second test was no less hair-raising than the first: <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\">\u201c<span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>This experience was more frightening than the first because local overheating had caused combustion chamber joints to leak and the escaping fuel vapour took fire above the engine. Altogether a petrifying situation &#8211; except for those who once more disappeared with record-breaking speed.\u201d<\/i><\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">This time, the problem was found to be a faulty fuel valve. This, too, was easily resolved, and after a few more successful tests Whittle and his team were ready to demonstrate the engine for Dr. David R. Bye, Deputy Director of Scientific Research at the Air Ministry. The demonstration, which took place on June 30, 1939, so impressed Bye that just weeks later, the Air Ministry awarded Power Jets a contract to produce a new engine engine &#8211; designated the W-1 &#8211; for an experimental aircraft to be built by the Gloster Aircraft Company. The aircraft, known as the Gloster E 28\/39 \u201cPioneer\u201d, was delivered to the airfield at Brockworth, Gloucestershire on April 7, 1941. By now a fully-qualified test pilot, Frank Whittle performed many of the initial taxi tests himself, using a non-flightworthy version of the W1 engine. Finally, the aircraft was fitted with the proper engine and, on May 15, 1941, flew for the first time with test pilot Gerry Sayer at the controls. During the flight, which <\/span><\/span><\/span><span style=\"font-size: small;\">lasted<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> 17 minutes, Sayer achieved a maximum speed of 560 kilometres per hour &#8211; only slightly slower than the RAF\u2019s fastest fighter at the time, the Supermarine Spitfire Mk.V. But while this was a monumental achievement, it was not the first flight of a turbojet-powered aircraft. Unknown to Whittle, he had been beaten to the punch two years before by a similarly brilliant and driven German engineer. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Hans Joachim Pabst von Ohain was born on December 14, 1911 in Dessau, Northern Germany. Like Frank Whittle, von Ohain first conceived of the jet engine as a 22-year-old university student; otherwise, however, the two men\u2019s career trajectories could not have been more different. After obtaining his PhD in Physics and Aerodynamics from the University of G\u00f6ttingen in 1933, von Ohain <\/span><\/span><\/span><span style=\"font-size: small;\">became a<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> junior assistant to Robert Wichard Pohl, director of the university\u2019s Physical Institute. In 1936, he patented his jet engine concept and, along with automotive engineer Max Hahn, attempted to build a working example. Unfortunately, Von Ohain and Hahn could not get the fuel to ignite and burn stably in the combustion chamber, causing flames to shoot out the back of the engine and the electric starter motor to overheat. Nonetheless, their work soon caught the attention of Ernst Heinkel, founder and director of aircraft manufacturer <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Heinkel-Flugzeugwerke<\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> in Warnem\u00fcnde. On Pohl\u2019s recommendation, Heinkel hired von Ohain and provided him with the funding to continue his jet engine research. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">By February 1937, von Ohain had assembled a new engine called the HeS 1, fuelled by hydrogen gas. Though the engine ran well, the hot-burning hydrogen quickly damaged the metal components. Von Ohain thus modified the design to run on kerosene, producing the more reliable HeS 3, which could produce 4.9 kilonewtons of thrust. To flight-test the new engine, Ernst Heinkel tasked his two best engineers, Walter and Siegfried G\u00fcnter, to design an experimental aircraft, dubbed the He-178. 7.6 metres long with 7.3 metre long elliptical wings mounted high on the fuselage and a conventional tail-dragger undercarriage, the He-178 was powered by a single HeS 3 engine mounted behind the pilot, fed through an air inlet mounted in the nose. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">The He-178\u2019s maiden flight took place at Heinkel\u2019s Marienehe aerodrome on August 27, 1939, just five days before Nazi Germany invaded Poland. Present on the field that day were several top officials from the <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Luftwaffe, <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">including <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Generaloberst <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Ernst Udet and <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Generalfeldmarschall <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Erhard Milch.

A mechanical fault had forced Warsitz to fly with his landing gear extended, limiting his top speed to only 598 kilometres per hour &#8211; only slightly faster than Germany\u2019s standard fighter, the Messerschmitt Bf-109. Furthermore, the rapid advance of German forces across Europe convinced military planners that the war would be <\/span><\/span><\/span><span style=\"font-size: small;\">quickly<\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> concluded, making new aviation technologies like jet propulsion unnecessary. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">By the time the <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Luftwaffe<\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"> changed its mind about the value of jets, other aircraft manufacturers had already leapfrogged ahead of Heinkel and von Ohain\u2019s first prototypes. In 1940, for example, designer Anselm Franz of rival aircraft manufacturer <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Junkers Flugzeug-un-Motorenwerke <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">developed the Jumo 004 engine, which used a more efficient axial-flow compressor in place of von Ohain\u2019s centrifugal-flow compressor. BMW and Brandenburgische Motorenwerke or Bramo also developed similar engines, while the Reich Air Ministry or RLM secretly contracted Junkers, Messerschmitt and other manufacturers to develop their own jet fighters. Despite being left out of this request, Heinkel proceeded with the development of a twin-engine jet fighter called the He-280, which incorporated a number of key innovations, including tricycle landing gear and a pneumatically-propelled ejection seat &#8211; the first in aviation history to save a pilot\u2019s life in an emergency. After lengthy delays caused by developmental difficulties with its intended engine, the HeS 8, the He-280 finally made its maiden flight on September 22, 1940, becoming the world\u2019s first jet fighter to take to the skies. Subsequent test flights proved the He-280 to be a superbly swift and agile aircraft, easily outmaneuvering the Luftwaffe\u2019s best convention fighter, the Focke-Wulf Fw-190, in mock combat. Nonetheless, the RLM ultimately rejected the design, and rival firm Messerschmitt\u2019s Me-262 <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Schwalbe <\/i><\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">became the world\u2019s first operational jet fighter, entering service in April 1944.<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Thankfully for the Allies, several factors prevented the Me-262 from having a significant impact on the war. Chief among these was Adolf Hitler, who, believing that Germany should always be on the offensive, ordered that the new jets be used for ground attack, a task for which they were ill suited, rather than shooting down Allied bombers. And even when the Me-262 was deployed in its proper role as a fighter, technical and logistical problems prevented the aircraft from reaching its full potential. The primitive metallurgy of the Junkers Jumo 004 engines gave them an extremely short lifespan, requiring them to be removed and overhauled after only a handful of flight hours, while Allied bombardment of factories frequently interrupted production of new engines and spare parts. Worse still, chronic fuel shortages caused Me-262 squadrons to spend most of their time on the ground.<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Meanwhile, in Britain, Gloster developed its own jet fighter, the Gloster Meteor, powered by two of Frank Whittle\u2019s upgraded Power Jets W2 engines. First flown on March 5, 1943, the Meteor was the Allies\u2019 only operational jet fighter of the war, though it never saw combat against manned aircraft. Instead, its 970 kilometre per hour top speed made it invaluable for chasing down the German V1 flying bombs that terrorized southern England between June 1944 and March 1945, with Meteor squadrons scoring 13 victories by the end of the war &#8211; and for more on this, please check out our previous video <\/span><\/span><\/span><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>A Wingtip and a Prayer: the Insane Way British Pilots Defeated Germany\u2019s Secret Weapon.<\/i><\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">While the Meteor was under development, the British government secretly shipped a Power Jets engine and a handful of engineers across the Atlantic to the General Electric facility in Lynn, Massachusetts, in the hopes that the Americans could improve the design and put it into mass production. The GE team that received the engine were sworn to secrecy, as former engineer Joseph Sorota later recalled:<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\">\u201c<span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Our colleagues called us the Hush-Hush Boys. We couldn\u2019t talk to anyone about our work\u2026The FBI man warned me that if I gave away any secrets, the penalty was death,\u201d<\/i><\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Indeed, the project was so secret that no outside contractors could be brought in to modify the workshop or build test stands and other equipment, forcing the engineers to carry out this work themselves. They were also hampered by a lack of adequate tooling:<\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\">\u201c<span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\"><i>Our wrenches didn\u2019t fit the nuts and bolts because they were on the metric system. We had to grind them open a little more to get inside.\u201d<\/i><\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Despite these difficulties, in March 1942, just five months after the project started, the GE engineers successfully bench-tested their redesigned engine, the I-A, producing 5.8 kilonewtons of thrust. The I-A was subsequently installed in an experimental fighter aircraft, the Bell Aircraft XP-59 Aircomet. In keeping with the top-secret nature of the project, during ground handling the XP-59 was fitted with a dummy propeller to disguise its true nature. The Aircomet made its maiden flight on October 2, 1942 at Muroc Army Air Field in California &#8211; today Edwards Air Force Base &#8211; with test pilot Colonel Laurence Craigie at the controls. Unfortunately, the first American jet proved underpowered and never entered service, though GE would later refine its I-A engine into the J31, the first jet engine to be mass-produced in the United States. In 1945, the Lockheed P-80 Shooting Star became the United States\u2019 first first operational jet fighter, serving with distinction in the Korean War alongside other early jets like the North American F-86 Sabre. The commercial aviation market followed suit in 1952 with the introduction of the British de Havilland DH.106 Comet, the world\u2019s first jet airliner. Within just a few years, the age of the piston-engined aircraft had finally come to an end; jets now ruled the skies, making the globe just a little bit smaller with every passing year. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span style=\"color: #000000;\"><span style=\"font-family: Times New Roman, serif;\"><span style=\"font-size: small;\">Of course, jet engines have come a long way since those early days, seeing dramatic improvements in thrust, fuel efficiency, and reliability. But that is a story for another time. <\/span><\/span><\/span><\/p>\n<p align=\"LEFT\"><span class=\"collapseomatic \" id=\"id69f1518471cff\"  tabindex=\"0\" title=\"Expand for References\"    >Expand
