A page from my logbook. November 4, 1993. Buno 159452, a block 80 airplane, built in the early 1970s. RIO was Dave Shugru.. the 2K2 mission code was a maintenance check flight. Because a new engine had been installed, our job was to validate that it worked correctly throughout the flight envelope. This included a Mach run up to minimum of 1.5.
But on that day (cold weather helped) we pushed it well beyond the minimum.
