Tim,
I've been high, but not that high shooting...I do know that at 65K
feet, the exposure is normal with high contrast. Might I suggest you
go to http://www.dfrc.nasa.gov/PAO/ and query those folks as to where
you can go to get an answer. I used to work with them and if you ask to
be directed to where you could get the answers....I would imagine JSC
(Johnson Space Center) would be a good place if they could hand you off to
them.
I was working with an astronaut years ago on camera technique for
aerials from jets, and they teach all that stuff to the astronauts.....
