"BTW, what do you think caused the cracked windscreen? Birds don't fly at 27K, right?"
Ive had 3 cracked windshields in a B1900, and 2 in a BAe 146... every time I had a windshield crack, it has only been on layer of glass and hasnt caused any pressurisation problems. We did descend and reduce the cabin diff every time though.
You are right! Birds dont fly that high, these sort of things just happen...
On another point, if it was anything like the B1900 flying I did a few years ago... we didnt have an autopilot. If these guys had an autopilot, and it was on Alt hold... more than likely, they might have ended up meeting the same fate as Paine Stewart a few yrs back... scary. 'Falling' out of the sky, was probably the best thing that couldve happened for these lucky fella's...
