I saw AF
-1 landing at EWR
back in '99, bringing President Clinton into town for some speeches.
Since 9-11 AF
-1 usually lands at McGuire AFB
in Central Jersey when President Bush comes to the NYC area.
When President Bush went to the WTC site to meet with recovery workers on 9-14 security was TIGHT. He landed at McGuire AFB
where he was met by Mayor Giulianni and Governor Pataki who flew helicopters out to greet the President.
A bunch of different helicopters then flew the 40-45 miles from McGuire AFB
to the Westside heliport, and then drove down the Joe Dimmagio West Side Drive to the World Trade Center recovery site.
I've often seen two Marine Corps 1 helios flying in formation with two Marine Corps Chinooks prior to a Presidential visit to the area, they fly right over my house.
