Vasco,
Re aborted take-off.
During the take-off run the handling pilot flys and the eng and the non-handling pilot monitor the engine. Above V1 the flying pilot should have had both hands on the 'stick', in order to prevent aborting after V1. (Like we used to practise in the Sim regularly)
For those not used to the term V1 it is effectively the position on the runway, related to a speed, before which there is not enough room to take-off following an engine failure and after which there is not enough room to stop.
That was good enough for me before anyone gets pedantic.
