Does anyone know the Cd values .vs. velocity for the Shuttles main tank?
My feeling is that we need a compact shape to get there, and some sort
of deployable squatness to get back.

0.7.  I use only numbers I'm sure we can make, and we've already
demonstrated CD = 0.7.

Depends on the size of the vehicle.  Remember square/cube law becomes
significant at small scales, especially with that squat shape on which
Michael insists.  I'm beginning to think squat *and* small won't work. >>
