Then the next step is to use that data on a Heads-Up Display (HUD),
and show the velocity vector, so that you have a "bug" which shows
exactly where you would get to with your current state. Having flown
a Harrier simulator which has that, you'd be amazed how valuable that
is. Then there's the pitch ladder, which isn't that useful to a
glider, and the speed and altitude tapes. And, somewhere there's a
secret government program to make almost exactly this instrument.

Hey, we're dreamin' here.
