If I read your logic, the jet is unmoving because it is in steady flight
(not circling), so it stays in one position relative to the glider. Whereas
the glider is circling and so moves back and forth to some extent. Well,
given the small diameter of a thermalling glider, I think for all intents,
the glider would have been effectively a small dot in the sky except for the
last seconds. The power pilot had some clues, but it is still darn
difficult to see other gliders sometimes. Heck, I've been in thermals where
the other glider never saw me.
