Everything changed in 1936, when with the help of two ex-RAF officers and an engineer, with funding from an investment bank (O. T. Falk and Partners), the company of Power Jets Ltd. was formed. Based in the British Thomson Houston works at Rugby, work proceeded slowly - Whittle was still a serving RAF officer and support from the Air Ministry was non-existent. But on the 12th of April, 1937, the first run was made of the Whittle Unit (WU). Onlookers ran for cover amidst a "noise like an air raid siren" but the idea was proved. In the meantime, the clouds of war were gathering on the horizon, but still the Air Ministry was not interested, concentrating on more conventional designs for aircraft and engines.

Whittle would later say "Good thing I was too stupid to know this"! The constant fighting for support took its toll on Britain's efforts to get a jet aircraft in the air, however. The Germans, using a jet engine designed by Von Hain, had the Heinkel 178, a rather ramshackle affair using an axial flow turbojet (unlike Whittle's centrifugal flow design), in 1939 and the Italians just about managed to get the hopelessly underpowered Caproni-Campini N.1 into the air in 1940 (more of a pseudo-jet as it used a piston engine buried in the fuselage to power a turbine).

Work on the augmented W.2/700 engine stopped and Power Jets was nationalised and merged with the gas turbine section of the Royal Aircraft Establishment to form the National Gas Turbine Establishment. Whittle and most of his team resigned in disgust. It was the end for Power Jets (the old Power Jets' site at Whetstone is still in use today; the power generation division of GEC Alsthom is situated there and the old cooling pond is still utilised).

Incredibly, having given away the plans for the jet engine to the Americans along with much of the Miles M.52 research, the new government gave Rolls-Royce jet engines to the Russians as well, resulting in the quick development of the MiG-15 fighter aircraft. The stress of his constant struggles for support had led to a deterioration in Whittle's health and eventually in 1948 he retired on medical grounds. In his post-RAF career Whittle continued to work on gas turbines and then drilling machines, in particular working for Shell, filing several patents related to drilling equipment. He also advised the aviation industry (including BOAC and Bristol Siddeley) and later he moved to the US - his experience there during the war had showed him an atmosphere of openness and easy recognition of a person's achievements and this no doubt influenced his decision. His final work was as a research professor at the US Naval Academy.

The aircraft industry was worried about the new invention and desperately wanted to get involved despite their earlier lack of support or interest. Pressure brought to bear on the government resulted in Rover being given the contract to produce the W2 engine for the Meteor. With no experience in gas turbines, Rover quickly fell behind schedule and in 1943 Rolls-Royce were called in to replace them. With much aero engine experience, Rolls-Royce did a better job, but development should have been left to Whittle and Power Jets, who really knew what they were doing. The plans for Whittle's designs had also been handed over to the Americans, who built copies for use in the experimental P-59 Airacomet. Whittle worked with the Americans to help them and was impressed with the level of enthusiasm they showed - and remarked on how things would have been different if he'd had that level of support from British industry. Meanwhile the time and effort wasted meant that the Meteor did not fly until 1943 and was not ready to enter service until 1944.

However this isn't the smallest jet engine ever built - far from it. Some engines weigh just a few pounds but still produce more than enough thrust to power small aircraft such as a unmanned aerial vehicles (UAVs).
