No, you do need air, Mark! :-)

"Glide" is a relative term. "near crash" might be another. The
Dynasoar prototype and the Shuttle itself PLUMMET to earth. I've
watched the videos of the Gulfstream that is programmed for training
the astronauts to land at the Cape. It's pretty damn scary stuff. The
shuttle flies - but only in comparison to, say, a brick.

I'm amazed at the people who frequent this list. I watched a B-70 "to
failure" brake test at BF Goodrich. The brakes were liquid cooled. It
was pretty amazing. Nothing compared to some of the other tests I saw,
though, when I was in high school. AMAZING. I wish I could have taken
pictures. There WERE movies made though. I wonder what happened to
them?
