aero spacelines

The Aero Spacelines B-377PG Pregnant Guppy was flown to Dryden for tests and evaluation by pilots Joe Vensel and Stan Butchart in October 1962. The outsized cargo aircraft incorporated the wings, engines, lower fuselage and tail from a Boeing 377 Stratocruiser with a huge upper fuselage more than 20 feet in diameter. The modified aircraft was built to transport outsized cargo for NASA’s Apollo program, primarily to carry portions of the Saturn 5 rockets from the manufacturer to Cape Canaveral.
