GeoffSM1,
THANK YOU SO MUCH for finding the audio for UA733 from the other day! My buddy was on that flight and reported his plane flying over another one taking off on the crossing runway which jives with what we heard. Controller called the Go-rround almost immediately after clearing UA720 to take off on 1R. So no incursion but obviously he thought things were too close and he called the go-round on UA733.
Many, Many Thanks!
Mark
P.S. Can you explain what you thought was interesting on the 2nd clip you posted?
