So it looks as if someone who wasn't there has better info than the one supposed to be at the holding point !
I don't get this one who are you refering to?
And the ATC did not ask him to stop he did it on his own
So ATC did tell him to "Expedite Take Off!" as he was already rolling? Or something completely different, if so what? I don't get this too because it will always be the pilot who stops the plane not ATC, but what was it that made the pilot stop? That is the question here.
