There's a 2.25" hole in my panel for a transponder but there's an even
bigger hole in my wallet preventing me from filling the panel hole.
(Although the priority is rising.)

Technology like Mode S and/or ADS-B will replace Mode C transponders so
investing in Mode C now may be an expensive short term solution.

The "system" didn't work but the parachute did.

"Right of way" is a slippery concept but in this case, the glider was
apparently thermalling so it was a semi-stationary object hit by a fast
moving jet. It seems logical to me the burden of responsibility falls on
the Hawker pilot. This is backed up by FAR's

If, as is being speculated, the transponder installed in the glider was not
yet properly tested for use and therefore not turned on, I don't think there
is any culpability for the glider pilot. In fact, he should get credit for
trying to do the right thing.

This incident should be a reminder to jet pilots that "clearing the flight
path" when flying below FL180 in VMC is an absolute necessity. The "system"
simply can't and won't protect you under VMC.

I have had heavy transport aircraft fly close by me in situations where, in
my opinion, there was no reason for them being there. For example, a jet in
American Airlines livery flew under me when I was flying below the rim of
the Colorado River gorge in western Colorado. It couldn't have been more
than 1000 feet AGL. In another case, I was below the peaks of the
Contenintal Divide when a jet in United Airlines livery came through a notch
in the ridegline clearing his shadow by only a few hundred feet.
Presumably, no passengers were aboard in either case.

An actual collision is not the only danger. Wake turbulence left by a heavy
will also damage a glider.

Be careful out there.

Don't you have to *see* the other aircraft before you can give way?

Unless TCAS or radar vectors are involved, yes.

As has been mentioned by other posters in this thread, if the glider
didn't have a transponder the jet's TCAS wouldn't have seen it, and the
glider's profile might make it hard to spot.

Agreed.

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.

20 years ago, I lost a friend in a mid-air collision. He was flying
his glider at 11,000 in eastern Washington ( ground elevation about
4000'). He was hit by a Piper Arrow, that had four occupants. No
survivors. Either low or high speed, it can happen.
