This photograph shows an Aero Spacelines 'Guppy' outsize cargo aircraft with its massive hinged nose section swung open, exposing the cavernous cargo hold used to transport oversized rocket stages for NASA's Apollo program. Derived from the Boeing C-97 Stratocruiser airframe, these bulbous-fuselage transports were a critical, if unconventional, link in America's space program logistics chain during the 1960s, ferrying components too large for any other aircraft between manufacturing sites and launch facilities.
