At the museum there was also a special tour of a hangar that conatained many of the X planes that NASA and the Air Force used from the 40\’s onwards. Hightlights were the plane Neil Armstrong (X-15) tested and Chuck Yeager\’s X-1.
And you could go right up to them! Even more interesting were the number of planes that were the only 1 left after the others crashed ! There were two vertical takeoff planes – a Harrier (British built – hurrah!) and a delta wing type that was strapped to a vertical launcher plate.
An early stealth SR-71 was there along with the test vehicle that was little more than the engine, cowling, and casing.
