That's one of the more catastrophic engine fires I have seen. Usually they are Bennie in the sense that everything generally stays contained in the Nacelle. The crews are able to shutdown the engine and blow fire retardant in the N1 stage fan. This one did not stay contained in the nacelle area.

If I were to guess there was either a fuel manifold rupture near the nacelle jacket or possibly catastrophic failure of a hydraulic pump. My gut goes with the fuel manifold.

They are lucky they are not dead. If that plane got airborne there is a high chance that flames could have breeched the fuel cell. The pilots did a good job aborting the takeoff. That is most critical time during takeoff. Once you reach V1 you have seconds to either continue to take off or abort. A plane like this probably gets to V1 within 15 to 30 seconds , not a lot of time for indecisions.

Lt Col (Join to see) I was thinking the same thing -- that they're lucky the wing tanks didn't breach. I imagine even right now most of those people don't know how close they came to buying the farm. I don't know if the thing was taxiing or was in it's takeoff roll, do you have any more info on that?

It appeared it was during the initial power push to take off thrust when it occurred, from what I read. Does not seem that the plane started its takeoff roll. My guess throttles went forward the fire came on and then immediately they aborted. After that they probably initiated the engine fire on the ground checklist. The disturbing thing is that usually when the throttle is cut off and the engine fuel shutoff valve is pulled it usually extinguishes out after blowing the fire retardant.
