This morning Blue Origin successfully tested the crew capsule abort system on their New Shepard rocket, using the same booster (and spacecraft?) that has already flown 4 times. The abort, performed at Max-Q (maximum aerodynamic load) caused the capsule to transition twice through transonic. To the amazement of even Blue Origin's engineers, the booster also survived (and continued on to space, returned and landed as planned). As bezos said a few weeks ago:

"This test will probably destroy the booster. The booster was never designed to survive an in-flight escape. ... If the booster does manage to survive this flight – its fifth – we will in fact reward it for its service with a retirement party and put it in a museum."

Though other rocket programs have tested their abort systems from the launch pad, this is apparently the first in-flight abort test since the apollo program.

Apologies for this strange video with Windoze desktop in the foreground. It's the only non-full-length I see online so far.
