The bulbous silhouette of the Aero Spacelines 'Pregnant Guppy' dwarfs the automobile parked beneath its nose. Built in 1962 by modifying a Boeing 377 Stratocruiser, itself a descendant of WWII-era Boeing bomber technology, this remarkable aircraft was created to airlift oversized rocket stages for NASA's Saturn program, playing an unsung but vital role in the American space race.
