: I inquired about their use in gliders (practically
: no weight and could go in fuselage behind wing) and
: someone told me they would not give a strong enough
: signal for aircraft use owing to the speeds involved.

I have heard that a military ATC who visited one site where I fly said
that it would make a considerable improvement to the radar return from
a glider. It's on my list of things to do.
