"Families have called for testimony from Boeing Chief Executive Dave Calhoun, his predecessor and other current and former employees as part of their legal case in Chicago, court documents show."
Sounds like both.
As for "ruptured fuel line", one of the main items on engine out checklist with fire reported, is to cut off fuel and extinguish the fire. I can bet they tried all 3 extinguish techniques, yet clearly it did not go out. Hence ruptured fuel line feeding it.
How are you so sure it's a "no". Sorry but I have seen/heard FAA, NTSB and T.C. inspectors say the same "no" when just looking at a craft, yet they come to find out, it was a yes when it was tested.
As I stated " if any, may have ben on the verge of failing." I did not state they would fail. Many look at a few pictures and think/state "oh that's nothing and will buff right out" until they take things apart and find out there was more damage than anticipated. There is a small tear in the wing behind engine 2, could it have increased in size while continuing to fly?
ETOPS is also taking into account no other or minimal, damage to the aircraft. I am reserving judgement on how bad it could have been over the ocean. Seeing that large gapping hole in the fuselage, ruptured fuel lines, and damage to the wing, I want to hear what other systems, if any, may have ben on the verge of failing.
True. It may seem like a blunder but considering the amt. of cargo handled, and the maintenance and manufacture facilities at Mirabel, it may have been one of the best ever.
