Why do you automatically assume the Hawker pilot is at fault?

Because it is my understanding that federal regulations grant gliders
right-of-way over powered aircraft.

That is my understanding too, but that goes back to my original point
of ceding right of way. If the jet pilot didn't see the glider (until
it was too late?) how would she have given way to it? This sounds to me
like a classic see-and-avoid issue resulting in a MAC with,
fortunately, no loss of life.
