#4 Reentry autopilot

[Chode]

I've started working on this. Right now, I'm thinking that
you could start by entering the P61 program, and the
AGC would display information based on your current
trajectory (entry angle, max G, landing point, etc.)

If you just proceed through all the steps, the autopilot
will take control to fly you down in a realistic way. The
next higher level of sophistication would be to allow for
the astronaut to change the landing point and other
parameters (within limits).
