We are seeing a replay of the 20's and 30's. there's work on rocket
powered
air racing; the X-prize was won and Diamandis is working on another more
lofty (pun intended) goal. This is one way aviation technology leaped
ahead in the past, and how space technology may leap ahead in the future.
Note that these are private enterprises.

You have to be kidding! If you think that the present proposed rocket
racing is going to lead to new advances, you are badly out of touch with
reality.
