in the beginning of the movie when Danny and Rafe are playing chicken with their planes they are supposed to be at a Long Island Air Field. several times during that scene you will see Mountains in the background. I lived on Long Island for 21 years and never seen any mountains like the ones in that movie. Maybe hills on the Island but not mountains. Obviously not filmed on Long Island but you would figure they would have digitally removed them for the final cut. Other than that, Excellent Movie.
