Saw an article today about an aircraft that would change it's buoyancy, so
it would float up like a balloon and then change buoyancy and glide down.
Interesting stuff, although I doubt we'll see it anytime soon. Is something
like this even practical? The article says they take the aircraft up 10
miles to get 400 miles range, I would think ATC wouldn't like the idea of a
free balloon (which is what it would be at that point) up in the flight
levels.

A blimp pakaged in such an areodynamic package and the 40:1 glide ratio
from something that drives air compressors is a bit tough for me to chew on.
