Really good SR-71 Blackbird / YF-12 video

I just wanted to share this video, in case some of you haven't seen it yet.

It shows some of the aerodynamic testing done on the aircraft, using the aircraft itself as a " flying wind tunnel ".

One of the findings was that at Mach 3 speeds, skin friction drag accounts for 1/3 of the total drag on an aircraft.
