165 or so kts, BOOOM right under one's arse, aircraft swerves a bit, tyre bits fly into the e and e compartment giving some weird EICAS, destroys the downlock sensor......what to do? You got a second and half to decide. Engine failure? Tire failure? Or what? The right answer is probably either stay on the ground or go fly. Book answer probably one should go fly, real life answer with a second and a half analysis, stay on the ground with sensory information given. Interesting thing is, that thing stopped with around 300 meters remaining. That's what's impressive. Sadly, there may be some extra training for these chaps refering to the above Boeing FCTM. "Of course you should have known it was a tyre failure".
