It obviously followed the X-1 (high altitude, extreme speed experimental aircraft dumped from a mother plane before ‘rocketing’ off into the wide blue yonder. (Pilots must have had some serious gumption!)
I believe this MAYBE a movie prop used in a film with Clint Eastwood… I wish I had paid closer attention and knocked on the fuselage… MAYBE it was the real thing????
After some chat here I have started to search online to connect the pilots name with the program but no luck so far.. Off to Wikipedia aren’t you!
