A month or two ago Blue Origin got their first full BE-4 engine put
together (and I think there were a couple more right behind that, so
they may have gotten three of them together). Today that engine
apparently energetically disassembled itself on the test stand.

Just what power levels they were testing is currently unknown, but I
wouldn't expect them to be pushing max power through them this early
after getting them built.

It may not be a major deal and these sorts of things do sometimes
happen during testing, but it surely isn't a GOOD sign...


Drat. Meant to include a link with that.

It is disappointing, but Bezos has deep pockets and has reportedly
funded building several copies of the development hardware. The big
question is how long it will take them to identify what went wrong and
to modify the next engine in line to fix it. Time will tell.

That said, I'm sure the AR-1 team is sending Blue Origin their
condolences.
