For a flying pilot to have a "feeling," seconds after V1, that the airplane won't fly is imaginary. . . and to discontinue the takeoff after rotation is suicidal.
Well, clearly it wasn't suicidal!
A 'feeling' or 'hunch' or an 'intuition' is one of the ways our imperfect brains make decisions. Research shows it to be a pretty accurate one.
At the time of rotating the aircraft to takeoff, the pilot flying decided to reject the takeoff because he believed the aircraft was unsafe to fly.
If that was what he truly felt, he made the right call. Bear in mind that he has some idea of the runway length.
Twice in my career I have had 'hunches' and acted on them as though they had been confirmed by hard data. Many of us will have had experiences like this. In both cases the 'hunches' proved correct.
