i was fortunate enough to be on the flight - great experience with water cannon salute and all.
this .mp3 captures most. it is missing the captain taking over comms from the FO for a second and giving kennedy tower a little speech (which must have been before tower said "UA535 thank you" at about 1:37), as well as takeoff clearance. the liveatc scanner was on another tower frequency at those times. i tried pulling up the isolated 123.9 tower frequency (in addition to KJFK tower 2 and gnd/twr), but only can manage the 'file not found' on all of those.
