I was loading AWA #660 outbound @ B-23. ServisAir's Lav Truck had white smoke pouring out for a few minutes. They moved it out of the way with a Bag Tug. It occured just after BA
288 arrived on B-25. There wasn't any visible fire, though. You must have picked that up on the PHX
Aviation band? That was around 15:30 on Election Day.
