That is quite possibly one of the most awesome things I have ever seen. Imagine being able to fly on the verge of space, where the only trace of atmosphere, are ionized particles and ozone. like a flying fish, leaping out of the ocean into the air for only a brief few seconds. The U2 has now captivate me, I have never seen footage like that before and the ability to skim through the atmosphere like that is a very humbling experience knowing that only 108 years ago our first aircraft was skipping off the dunes at Kitty Hawk. I am intensely interested on how the engine systems work on that aircraft, excellent find. Also I really wonder what an ejection at that altitude would do a person.
