For those of you who have read the news, you would have noticed an article about the Airforce One jet doing a flyby in New York for a photoop. For whatever reason it was done, and strange enough, with all the people performing the act, this was in the books for ultimate stupidity.
Given the September 11 attacks, any city in the world would be paranoid over a plane flying on low altitudes. This chosen city was no ordinary city, this was New York, and flying a 747 in low altitudes is definitely a terrible idea. Proof of this is the reaction of everyone who witnessed the plane. People panicked, evacuated buildings, in short, everything was disrupted.
