LINDBERGH, CHARLES, Aviator. Autograph letter signed to Juan Trippe, President of Pan American Airways, Bordeaux, 20 December 1963, 4 full pages, written on rectos only, excellent technical report on test flights of the prototype Pan-Am Dessault Mystere: "...[R]esults...were highly satisfactory. Present stall charactistics...are still very good...I am much impressed with the appearance of the plane...The lines are good and the cabin and cockpit well designed. It has a good 'feel' for both pilot and passengers and showed no dangerous tendencies during the stall tests...This is an attractive plane...I arranged for the drag chute to be released on the second landing...The question of a drag chute vs. thrust reversers is somewhat complicated...For a plane that I was to operate myself, I would not want thrust-reversers...[but] many pilots on flights including the use of marginal-length air-strips will argus strongly for thrust-reversers..." -- LINDBERGH.
