Thanks Dozy - I had to Google that one (the only "Hoot" Gibson I knew of was the Space Shuttle pilot - I have a SS model around he that he autographed
).
After I found the Wiki, I vaguely remember hearing about that incident (I was a young, fresh faced engineer at the time) but didn't know it had become so controversial. There was a story going around Boeing at the time that the crew "accidentally" erased the voice recorder after landing (no idea if it has any truth). Doesn't sound like the NTSB's finest hour
.
