No such request was heard on the audio, and a crew would not/should not do a run on the runway without clearing that with the tower, first.

It's clear that the southwest flight shouldn't have been released with the FedEx flight on a Cat III. It sounds, from the audio, like ATC was pushing runway utilization as tight as they could, which is setting up for something like this to occur.

A call from an airplane going around should not be to the aircraft taking off to abort (reject: it's a Boeing). That's not a call to be made by the aircraft initiating a missed approach, and certainly not a call I'm aware of any training department or organization using as a standard. The only person who should have called to reject the takeoff with Southwest is one of two in the cockpit; otherwise the tower controller might have cancelled clearance, but certainly should not call for an "abort." The pilot of the FedEx airplane shouldn't be calling "abort," either. Fly the airplane you're in, not the other guy's aircraft.

Better to go missed earlier than later, in this case, and they did.
