A Pilots worst nightmare...happened at Manchester Airport a few months ago but this video shows it brilliantly.
It was scary because it is right in between V1 and V2 .
Pilots of large multi-engine aircraft calculate a decision speed (V1) for each takeoff that dictates action to be taken in case an engine fails. This speed is determined not only by the above factors affecting takeoff performance, but by the length of the runway and any peculiar conditions, such as obstacles off the end of the runway. Below V1, the takeoff is aborted; above V1 the pilot continues the takeoff and returns for landing. After the co-pilot calls V1, he/she will call Vr or "rotate," marking speed at which to rotate the aircraft. The Vr for transport category aircraft is computed such that three seconds after rotation is initiated the aircraft is in the liftoff attitude and at the liftoff speed. Then, V2 (the safe takeoff speed) is called. This speed must be maintained after an engine failure to meet performance targets for rate of climb and angle of climb.
