This should be a good documetary. Looks like they have new footage compared to earlier docs. over the years on the same subject. The X-1 hangs in the Smithsonian Air & Space Museum in D.C. and looked rather dusty when I saw it in '16.

One thing that is never pointed out is that when Yeager broke the 'sound barrier' at 40,000ft. it happened at about 660 MPH not the 761 mph which is the speed of sound at sea level.
