text_A: By June 1939, Power Jets could barely afford to keep the lights on when yet another visit was made by Air Ministry personnel. This time Whittle was able to run the W.U. at high power for 20 minutes without any difficulty. One of the members of the team was the Director of Scientific Research, David Randall Pye, who walked out of the demonstration utterly convinced of the importance of the project. The Ministry agreed to buy the W.U. and then loan it back to them, injecting cash, and placed an order for a flyable version of the engine.
text_B: Would Power Jets have gone out of business without an infusion of cash?
DON'T KNOW.
