I realize that, and I'm not trying to be a smart *****, I'm just saying that if the mount had failed while doing what it is designed to do (IE, Fly the plane) I'd say, "Ok, it was too weak to do it's job". But you weren't there to see what weird thing it may have done as it hit. Whatever it was, the firewall was not designed to stand up to that.

It WAS designed to pull the airplane, and to be as light as possible as it does so. It did it's job until something it wan not designed to do happened.

It's kind of like back in the 70's when they started to make cars that crushed on impact to save lives. Everyone thought it was a great idea. Then as soon as they had a fender-bender that cost $3000 to fix, they all complained about the "Crappy way they build cars nowadays"
