I have flown the demonstrator that was set up at Madras. A couple of
corporate operators were going to get together and buy one for Sun Valley.

I don't think that ever happened. It takes a controller on the ground with
the equipment and you get a special squawk and just fly it like any other
ILS.

Curved approaches are possible. There was military application as well. The
unit could be parachuted out and set up in 30 minutes to a remote location.

Have you ever heard of, or have any experience with a thing called the
"Transponder Landing System", a form of IFR approach using a
transponder? What is it, how does it work, does it work, do you have
to have a special "endorsement" to fly it, etc?
