look at this plane. It never flew but sure looked cool.
Enola Gay was the superfortress that dropped the atom bomb on Hiroshima
dual prop plane with pusher prop
A japanese cruise missile that was actually piloted by a kamikaze
Messerschmitt Komet plane with a propellor to run a generator
The tracking and data relay satellite that allowed coms with the space shuttle
A concept of gliding wing to land capsules on ground instead of sea
an early drone (KD2C-2 Skeet Target)
An F35 with its engine, very cool
This place is one of a kind, it totally deserves a stop in IAD when you're flying by washington, it's that good. Also, you may get plane fatigue after a while, because of how many artifacts they have. Either way, it's a do not miss.
