Don't know if this comes from SpaceX or SES.

But Musk is definitely good at coming up with 'interesting' new terms.

See RUD - Rapid Unscheduled Disassembly (aka Crash).

RUD has been a rocket engineering term for decades, same as e.g. lithobraking (slowing your spacecraft down by smashing it into the ground)

You can always learn something new on HN. ^^

I only ever read in articles about SpaceX.

I also like the concept of "engine-rich exhaust" (also known as "the engine is melting").

Pretty sure he nabbed that one from the KSP community.

Also its not so much a crash as the rocket falling apart.

The term is _much_ older than KSP (going back to at least the 70's)
