A month or two ago Blue Origin got their first full BE-4 engine put

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.
