The Pregnant Guppy had a humble beginning on the
proverbial cocktail napkin. One evening Conroy, Lee Mansdorf and others were discussing the problems
NASA were having transporting the rocket booster stages aboard ships through the Panama Canal and the Gulf of Mexico. Mansdorf had recently purchased several surplus
Boeing 377 Stratocruisers but was not really sure what to do with them. Conroy believed that they could take one of the Stratocruisers, enlarge the fuselage enough to hold a rocket booster and contract with NASA to fly the boosters from California to Cape Canaveral, Florida. Conroy and Mansdorf founded a company,
Aero Spacelines, to pursue the project. Conroy's drive to build the aircraft was so great, that when financing ran out, he did not: "Conditions reached the point where Conroy no longer owned his house, cars, or furnishings." By flying the Guppy on borrowed
aviation gasoline to the
Marshall Space Flight Center, Conroy was able to test fly the aircraft with
Wernher von Braun. On the basis of the test flights, contract negotiations with NASA began in earnest. The "
Pregnant Guppy" first flew on September 19, 1962, piloted by Jack Conroy and co-pilot Clay Lacy. When Van Nuys air traffic control realized that Conroy intended to take off, they alerted police and fire departments to be on alert. However the huge aircraft performed flawlessly, the only difference in handling being a slight decrease in speed caused by extra drag of the larger fuselage. Wernher von Braun stated that "The Guppy was the single most important piece of equipment to put a man on the Moon in the decade of the 1960s." Conroy then developed the
Super Guppy, which first flew on August 31, 1965, in Van Nuys. The
Mini Guppy was built in Santa Barbara, California, and was christened "Spirit of Santa Barbara", on May 24, 1967. Two days later, the Mini Guppy was carrying cargo to the
Paris Air Show, where in 1967, Conroy was awarded the "Medal of Paris" for the greatest contribution to aerospace for the prior two-year period for the Guppy aircraft. Conroy was the founder and president of Aero Spacelines, a subsidiary of Unexcelled, Inc. until he resigned in August 1967. == Conroy Aircraft ==
