There's a Super Guppy on static display at the Pima Air and Space
Museum here in Tucson off I-10 on the south edge of Davis-Monthan
Air Force Base and the "Boneyard",

It's grotesquely monstrous.

Yes, that was more or less my first thought upon seeing one at El Paso
years ago. There is something just *wrong* about it, less reminscent
of the sleekness of an airplane or even an airship than... I dunno; an
engorged aluminum tick. A giant-brained alien from the cover of an old
sci-fi paperback. Some deep-sea creature that was brought to the
surface too fast. You don't even expect it to be unloaded through
a cargo door so much as split open and spawn its cargo. Yet I
couldn't take my eyes off it -- just stood there recalibrating my
assumptions of what can and can't fly; not just in terms of the shape
but what those seemingly tiny wings and engines might accomplish.
Fascinating in a surreal sort of way.
