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.

I'm beginning to think squat *and* small won't work. >> _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
