An abort after rotation? very unlike!
For all those who fly commercial aircraft, you will understand the significance of continuing after V1. It is drilled into us at every simulator check... After V1... KEEP GOING!!!
V1 is a speed which separates the decision to continue the take-off or Abort!
For instance, if you try to stop after V1 there is a very good chance the aircraft will end up off roading and everyone knows aircraft are rubbish for it!
If the decision is to continue the Take-Off before V1 with a loss of an engine, there is also a good chance that you would not make the required 35ft screen height at the end of the runway/clearway.
Furthermore, V1 can NEVER be greater than Vr (Rotate speed). So if the Captain decided to Abort the Take-Off after Vr (in this case nose-wheel off the deck), I hope he had a bloody good reason. To be honest I was not there, but I would only abort a take-off after V1 if I was sure the aircraft wasn't going to fly. In this case it seems the aircraft was responding to inputs and I would have taken the problem into the air.
But hell, I would have loved to see that beast make a stop like that!!!
