Jones,
I'm not a aeronautical engineer but I have spent a lot of time flying
at high altitudes. 20km ~ 65,000 ft and propellers just don't work up
there (pure jets ram jets not fans are best). Also, even if they did
I don't see a zero ground speed as being possible at those altitudes
the basics of an orbit are litteraly that the object is falling
towards earth, but has too much foward momentum to hit, it keeps
missing. (very hitchiker, the secret of an orbit really IS to throw
yourself at the ground, and miss)
and that small of a height, youd have to have an ENOURMOUS speed.

correct?
Affirmative.
Maybe I will reword some of the content.
Uh, you *could* split the post.

OK I split the 70 kb chapter in half and sent it. I hope it comes
through, but in my Sent folder, half of it still shows up as being
Is it possible to position a large unmanned aircraft in
semi-permanent stationary quasi-orbit but at only 20-50 km in
altitude?
This concept would allow such things as a really cheap replacement
space telescope, or an antenna array high enough to broadcast
television and broad-band
