Great stuff!
There's a bit of 'willy waving' going on between SpaceX & Blue Origin, who recently successfully returned & propulsively landed their 1st stage after a sub-orbital delivery of a (so far) uncrewed capsule to 100.5 km altitude.
SpaceX's 1st stage separated at 75 km, but it was going sideways, down-range, whereas BO's just went straight up & straight down.
Whose is the greater accomplishment....?!?!
