Turns out that the aircraft itself started out on the West Approach feed. I loaded East and West approach and tower and mixed them to pull out all the pertinent stuff. Eliminated silences, so this does not run in real time. I left in all comms including other aircraft and ops vehicles.
This clip starts at about the 14:35 point in the original archive, when UA1463 checks in with approach. It cuts off a bit at the end when they are talking about parking, because it flips over to another half-hour of archive, and I didn't get around to loading that and splicing it in.
