Thanks, 2.5.
Pretty common sense stuff, really. Normally included (I would hope) in training. Anyone who doesn't realize that a high speed abort is a critical event shouldn't be controlling.
In the situation described by the OP, the Ajet has just commenced takeoff, should be plenty of time to stop it.
Of course, "just" might mean different things to different people...
To me it means within the last second or three, in this type if scenario.
