High-Fast
We were returning to home base after playing 'MiG' for some U2 protective gear tests. We had our full p-suits (fairly comfortable) so elected to go home hi-fast. I got to lead and at top of climb called 'Level FL730" to Miami Center who came right back with "And you weren't lying about your true airspeed, either!' We'd filled 1150 KTAS. F104As cruising in 3/4 AB at 100 lbs and 20 mi/min.
