As Ben pointed out, if the President came into Martha's Vineyard in a fixed wing plane, the answer is "Yes, Air Force One landed there", even if the plane he was in was my 310. The call sign follows the President. When the President is not on board, they refer to their tail number. When he is on a Helicopter, it's Marine One. The caveat to all that is that often more than one AF1 or Marine1 is aloft at a time for security/decoy reasons. Some international trips will have two complete floatillas of aircraft going at astronomical hourly fuel costs. Security in this country is a huge racket as well. We get very little reurn on a huge amount of security expense. That is where I propose we start budget cuts. It's ridiculous. Every addition dime we have spent since 9/11 has been a complete waste. Procedure and Rule wise, even public awareness wise, what we had in place generated all the information from the flight instructors that if acted upon when received could have prevented 9/11.
