Quote: "When I was a kid growing up flying light jets out of ORD we were lucky when we DIDN'T hit another airplane while pushing back - uphill in the snow! AND we had to get out and push it back ourselves!"
Haha, love it! :-)
With regard to this incident, all I know is that there have been plenty of times in my career when pushback has had to be stopped by either the groundcrew or ATC. In all that time (twenty plus years), I cannot recall a time where it took both of us crew to talk to the ground crew or 'deal' with the stop.
I am sorry but for an 'incident' like this (and yes, I am assuming that the aircraft did not even come particularly close to one another), occurring as it did in such a busy environment, the idea of filing a report would not even enter my mind. Obviously, in some peoples eyes I am not as professional as I like to think I am.
