Just watched a 2 hour program on the Skunk Works on the History Channel.
Secrets in the Sky: The Untold Story of Skunk Works (2019)
A very informative program. Did you know that the titanium for the SR-71 came from the USSR and a math formula, again from the USSR, was used to help design the F-117.
Edit: Right CR, fixed.
