The Aero Spacelines Super Guppy is an XL Cargo Aircraft used for transport of overside items and even aircraft. Mos famously used by the American Space Agency, NASA, the version I have made is the Super Guppy Turbine (SGT) uses Allison 501-D22C engines (engines similar to the ones used on the C-130 Hercules). There is only one Super Guppy still in service with NASA. The Super Guppy is a derivative of the Boeing Stratocruiser, and furthermore, the B-29 Superfortress.
