I received several options to get a manual. Thanks to you all.

I was leafing through a back issue of Soaring at SSA's W-O-N-D-E-R-F-U-
L online archive. Its fun to see what was happening 10-20-30 years
ago.

I then stumbled across a heads up display (HUD) for gliders. "Man", I
said to myself, "that is pretty cool."

Did anyone ever buy and use one of these? How well did it work? Why
don't we have one of these today?
