Thanks for the heads up. I have been downrange and am just catching up. FWIW XCor was founded by or is largely staffed by veterans of Rotary Rocket -- from the propulsion end.

They thought the engine design was the most marketable of RR's innovations. They have been pretty well funded AFAIK and have been flying the engine in a Long-EZ while a new airframe (spaceframe?) has been in conceptual design.

No reason the rotary recovery wouldn't work but it is a lot more complex than, say, the constant 250kt IAS glide used by other reentry vehicles.

d.o.l.
