Remoak,
"Why the engine failed isn't the issue. Whether the other one had a problem isn't the issue either. The real issue is why it was not possible to safely land the aircraft from 7000 feet, with a variety of possible landing venues available, plenty of time, and plenty of help available.
That's the only issue that I'm interested in finding answers to. The rest is interesting but ultimately not the core issue."
Merely a matter of opinion then.
The answers to the first two sentences with direct and indirect causes then give you the answer to the third in part...I would think. However, I could say the reverse. They're all interelated at an educated guess.
It seems you've already made up your mind methinks.
"There are two things wrong with this thread. One is the copious amount of over-wrought emotion, the other is the amount of mindless and ill-informed speculation."
No problem with the second point. The first however makes me shake my head in wonder at this point.
