While on vacation in southern NM I went to the airport at ELP to take photos of a friends a/c. While on the ramp I came across a still-flying example of a really rare bird, the "Super Guppy".
Originally designed for transporting large, unwieldy cargo for any client, it saw it's most of it's life in service for NASA moving large main-body parts for the Gemini and Apollo space programs.
This bird is still in NASA's care for testing and occasionally moving large pieces of cargo for the international space station. This is the only remaining flying version of this aircraft as all the other are either mothballed or in museums.
