We got married in Madrid, in a German Methodist Church, with the American vice-consul, who was a Filipino, to make it legal.” A website using the name "Mile High Club" regards the "Club's" "founder" as pilot and design engineer Lawrence Sperry as the "Club's" "founder", along with "socialite Mrs. Waldo Peirce" (Dorothy Rice Sims) citing their flight in an autopilot-equipped Curtiss Flying Boat near
Sperry Corporation (Sperry New Holland), avionics (e.g., gyroscopes, radars, Air Route Traffic Control equipment) (Sperry Vickers/Sperry Flight Systems), and consumer products (electric razors) (Sperry Remington.) In addition, Sperry Systems Management (headquartered in the original Sperry Gyroscope building in Lake Success) did a fair amount of government defense contracting. Sperry also managed the operation from 1961 to 1975, of the large Louisiana Army Ammunition Plant near Minden. Sperry bought out and continued the RCA line of electronic digital computers: architectural cousins to the IBM System/360. In 1983, Sperry sold Vickers to Libbey Owens Ford (later to be renamed TRINOVA Corporation and subsequently Aeroquip-Vickers).
