Ever been to a General Aviation airport near an SEC game? I once flew (as pilot) a plane full of UGA fans to nearby Auburn. There had to be 500 plus planes there. Seriously.
Terminal was on one side of the runway. A plane would launch, and 20-30 people would run across the runway. 20 seconds later repat the sequence.
Once airborne, they were like radial strobe lights fanning out in all directions.
