Given the fact that the U2-A only weighed 8 tons (or 3.125 times less than 25 tons); it had the power to go well over Mach 2 at sea level. But since it was flying over 100,000 feet where air resistance is practically nil.
Prouty does look down and to his right when he makes the claim @08:00 minutes that the U2 was hydrogen powered. He is making excessive hand gestures throughout the video. So, he appears to be lying when making these statements, using the traditional eyes to the right or the new excessive hand movement standard of lying.

The video seems to have been edited. The reference to the fire extinguisher sized tank has been removed. It has been changed to a propane tank. Either way it is a preposterous claim. Combustion requires oxygen. Hydrogen is not going solve the supposed flameout problems of the U2. Hydrogen is 4 times less energetic than kerosene. Prouty leaves out a lot of things in his U2 account. The most egregious thing is the fact that Powers was expected to commit suicide. The U2 pilots were supplied with a poison pen and were expected to use it to prevent capture. He also leaves out the fact that the U2 was rigged with explosives. It was set to self destructed after the pilots bailed out. The pilots believed that they would be killed , if they used the self destruct mechanism. That's why Powers manually bailed out of the U2. The fact that Powers lived is what shocked the U2 program people.
Interestingly the SNAP 8 reactor was about the size of fire extinguisher.
