Problem is, if you run out of runway before that can happen ...
This was mentioned over on the reject beyond V1 thread. Two overrun accidents in which the crew were unable to rotate the airplane and rejected were cited. An aircraft which fails to rotate due to misloading, mistrimming or flight control malfunction may leave it's flightcrew in the unenviable position of having to decide which is the lesser threat. Reject with an overrun or continue trying to get it in the air and potentially not make it.
There isn't nearly enough reliable information yet concerning this accident to make even an educated guess as to whether or not any of those things happened here. It's as good a guess as any and better than most though.
Some investigative work product which might tend to rule some potential causal factors either in or out:
Lab findings regarding the nature of any heat damage to brake units.
FDR traces indicating engine parameters.
FDR airspeed/time history
CVR transcript (translated)
An accounting of actual takeoff weight.
These bits of info are just a few items on a long list of things to be determined. I haven't a clue how quickly the investigation will proceed or how much will be revealed to the public, but I'll keep a watch on this thread for any updates.
