Footage of the Presidential helicopter convoy arriving in New York City at the Financial district Heliport.
First 2 Chinook (or Sea Knight) helicopters arrive with security and personnel, followed by 2 Marine One's (the real one and a decoy) landing. The President then heads into the Presidential Limo (Cadillac One) and the motorcade heads up the FDR Drive.
Fascinating sight!
(Since I had to use high zoom there is some shaking thruout the clip, sorry)
