After the fatal crash of Air India flight AI-171 near Ahmedabad on Thursday, a safety engineering expert said the aircraft appeared to have suffered a sudden and severe problem during the final phase of takeoff. John McDermid, a professor at the University of York, told AP that takeoffs can be aborted late in the roll, suggesting the issue likely occurred just before or shortly after liftoff, and was unmanageable.
