On one page Slayton has drawn two graphs as well as several mathematical formulas. Another page is a 16 x 11 Flight Data Sheet, dated September 2, for a “Cooling Sawtooth” test filled in by Slayton. In fine condition, with a light central vertical fold and some mild toning. Accompanied by a printed letter of authenticity from Ken Havekotte. Pre-certified Steve Zarelli and RR Auction COA.
