Great header for Chris's next DC article!
Mach 5, just another 12 or so to go

Is that a problem with the CCB model, or are they looking at airflow with an SRB attached in a Atlas 412 configuration ?
I think that is a prop line.

Does anyone know the anticipated gross weight, lift-to-drag ratio, and airspeed at touchdown? Crosswind tolerance? CG range? It would be interesting to compare the DC with the X-37 given their different configuratoins, though of course data on the latter is not very accessible.

It's the 21st Century and we have bolt & gasket technology. Don't confuse integral with permanent.Your point and humor failed because it is wrong. Don't confuse technology as a fix for proper engineering.Doesn't SpaceX jettison Dragon's docking adapter before entry?
