Controller needs a refresher on when to clear a plane into the ILS critical area when you are running CATII ops.

TCAS RA might have been inhibited.

I didn't hear SW request the TO, but it might have happened before that audio clip started.

Poor SA and ADM yes, but technically once cleared he owned the runway so ultimately it was ATC and FDXs problem. I'd guess the tower might get in trouble since he actually did not specify "no delay" and probably shouldn't have issued the clearance under those conditions. But pizza parties... old habits die hard. Yes SWA should have known not to delay. ATC may be in the habit of relying on SWA to not delay.

That's true, might have taken a moment to double-check the setup.

Which FAR's are you referring to, or is it in the AIM?

Southwest abort, with no call sign, and past a certain speed, in low visibility, Hmm.

If they had type 4 and I assume they did they would not have configured for takeoff until on the runway. I don’t know SWA procedures for low vis takeoff but I assume like other airlines it’s no checklists unless stopped and standing takeoff. Those three things alone account for the time it took to roll. Fault 1 - issuing SWA a takeoff clearance at all. SWA did not fail for telling the controller they were ready. Mini fault 2 - accepting the TO clearance when you know someone is on the ils in a low vis environment. Task saturated pilots read back WITHOUT processing. They may not have added one and one because of this. That’s why I say Mini fault. Kudos to purple for the go around and I understand their requesting SWA abort was questionable but understandable as they would come close in a go around. Should they have said it? Probably not.

This audio includes SWA checking in with tower, they simply advised ready to go. I did not sense a rush vibe, and they didn't even ask if they could get out before the heavy, they just checked in ready. If they had just switched over from ground, they might not have even heard tower clear FDX.

WSJ reporting they came within 1000'.

I had said in my initial post it didn't sound like a close call. Boy was I wrong. I'm guessing ATC will take the brunt of the blame for this. The SWA pilots may get a "WTF" call from the CP but I don't think they broke any FAR's.
