Always glad to be of service!

Yeah, Marc, whaddaya waiting for? Put all that SeaLaunch expertise to
work! ;-)

Quite possibly! But since the thing doesn't have a workable exhaust,

It's not just a matter of the "window" being flat, it's also a matter
of area! I have a 1/72 scale model of SkyDiver (Diver still being under
construction), and if the dimensions are supposed to be accurate, the
"intake/sensor window" would be about 2 1/2 feet (76 cm) vertically and 3
1/2 feet (106 cm) across! That's almost as big as the crappy bay window in
my new house, and way larger than any recon/sensor aperture needs to be! In
fact it would have to be extremely thick to resist the air pressure exerted
on it from high speed winds on it from the primary angle of attack!

Yeah, just as long as they don't blow up on landing like the Komets!
