At Chicago O'Hare, American 767 catches fire on runway - CNN.com

I work for a Commercial Aerospace parts supplier, so I'm obviously paying attention to this. Also, one of my best friends happened to have landed in Chicago, and was there when this happened. He just posted on Facebook earlier today with pictures and letting people know it wasn't him or his brother on that flight.



The fuel is just pouring out, that's why you see so much fire pooling. And remmeber, it was just starting takeoff, so that's the most fuel it will have.



Look what the heat did to the wing, with just minutes of a fire. Aluminum, loses a lot of its strength north of 400-500F. 7075Al (not sure if wings are made of that or not) melts between 890F-1175F. However, it wouldn't need to be that hot, it likely just underwent Creep due to the weight of its self, and dropping to approx 5-10% of it's room temperature ultimate tensile strength.

Yes, wings are mostly aluminum. The skins certainly are. The spars might not be but I think they are.

Almost everything is aluminum in the airframe. You can't really see what the heat did, what you see is soot from the fire and burned paint. However, it is highly likely that the wing is scrap, at least the skin.

Earlier there were reports of a blown tire leading to ingestion, that caused the uncontained failure. The shroud is supposed to be able to handle that. A part of the disc was launched about a half mile into a UPS building.
The new engines are designed to be able to withstand ingestion without causing pieces to depart from compressors or turbines. That is the real danger, those pieces can fly a mile or more. If that were the case there would be injuries inside the fuselage and evidence visible on the engine covers/shrouds.

Fuel pouring out feeding a massive fire and people going down the slides with their carry on bags and stopping 20 yards away to take selfie. :jpshakehead:

I believe the shroud will only contain the fan sections. The compressor disks are not shielded by the shroud. NTSB said it was a stage 2 disc that failed. I am not sure if this disc is located in the shrouded section.

I just told my wife about this and as to the cause, she asked if Led Nessman was around and if this might have been caused by a turkey?
