Oh yeah, and the first aircraft that was converted into a "Guppy" was the Boeing 377, back in 1965... The Canadair CL-44 followed in 1969, and the A300-600ST first flew in 1994...
I'm not a Boeing freak, I'm more of a Boeing fan, but these are the facts

Oh, and the A380 idea isn't so original either, the first operational (I think) double-decker was the
Breguet 763 Deux Ponts, and in the early 1990's, McDonnel Douglas started work on the
MD-12 double-decker, wich was due to fly in 1997.

Looks familiar?
