NASA has released a redacted report on the recent Starliner fiasco. Astronauts parked in space while they waited for a ride home, while and after they decided that Starliner wasn’t presently suitable for manned space flight.

Normally, we expect ‘redacted’ reports to exclude names and indentifying information, but this is different. Sample:

 due to the valve  -redacted- overheating

and

since flow is controlled by -redacted- swell contribution to resistance change would be negligable.

WTF? Does anyone have any idea what kind of information is redacted from that report?

Your first sentence is, “… due to the valve solenoid overheating”.

Your second sentence is “since flow is controlled by trim orifice and seat swell contribution to resistance change would would be negligible.”

Why are these things even redacted?
