So what came the first, the chicken or the egg?
Did she break up because of the RTO, or did they RTO because of the break-up?
We don"t know yet.
But one can speculate reasonably, that had they RTO because of the break up, that the aircraft would not sit there broken in three pieces but all three pieces pretty much in line. So I would guess, the break up happened after the overrun.
Belgian news reports quote the pilots "hearing two loud bangs and after that a loss of power".
