AF1 spotting tips:
--When trying to capture shots of Air Force One, concentrate on AF1 and pay no attention to whatever JFK ops are doing nor to any other planes
--Use a scanner. Listen to NY Approach first. When she gets handed off to Final Approach or to Tower, switch accordingly.
--AF1 is usually much faster approaching the airport than any regular airliners. Times are compressed.
--Use LiveATC to listen to the departing airport and track her as much as you can via LiveATC.
--When she makes first contact with Approach Control, she will announce the RWY preferred. Unless a miracle happens, Tower will honor any runway requested. Likely arranged ahead of time and likely an SS agent is standing next to the Tower controller
--Get rid of family and ALL friends if you are really serious about catching her. Otherwise, follow one of the likes of Moose, Eric, Senga, Tom Turner, etc.
