Really fuzzy thinking… just because you get away with something and perhaps beat the odds, doesn’t equate to the best action. In a case like this I would think the correct action would be the one that would represent the least risk – and that begs the question as to whether is is better to risk a crash on take-off with a full load of fuel or land later on a blown tire and more warning for emergency response crews, etc. Lots of aircraft have landed on blown tires. Would be real interesting to know the risk profile for both scenarios…

Just because the aircraft was beginning to lift the nose, that does not mean that it had enough speed to rotate or to safely climb out. The nose wheel can lift at Vmu prior to reaching V1 (abort/commit speed) and Vr (rotation speed), the speed at which the aircraft can attain V2 and climb safely with an engine out. A tire blowout would undoubtedly cause a situation where a VERY quick decision (like in one second or less) had to be made in a crisis mode with very limited information – bang, something happened, fly or abort. Pilots aren’t perfect, but these guys (and gals) train for stuff like this. If he knew he could abort, and the outcome seems to support this, it was probably a reasonable decision rather than risking trying to achieve flight while not fully knowing the condition of the aircraft at that moment.

There are too many strange accounts, thus far. Why do some media accounts mention a “crash?” There’s a huge difference between an “aborted takeoff” and a “crash.”

Some of the passenger/witness accounts – for whatever they might be worth – suggest that the aircraft stalled during the takeoff “lift-off.”

Blowing a nosewheel tire is a rare event, especially that late during a takeoff roll. The standard maintenance & pilot inspections of the aircraft should have revealed any tire flaws. In theory, the aircraft “lift” at that point during the takeoff would relieve pressure from the nosewheel; lessening the chances of its failure. Add the chances of a second tire failing; with the nose-gear collapsing.

Just given where the aircraft came to a stop, the suggestion is that the pilots have some really serious explaining to do.

The first question should address the pertinent wind conditions during the takeoff roll. The media images of the “flying” aft escape slide suggest a high cross-wind. Was the “cross-wind component” in excess of the aircraft limitations? Were the pilots intimidated into taking a dangerous risk? Or, did they just “goof?”

In any case, given the big-money environment, this event will probably “… go political.” It’s a story worth following.
