No one panic! The helicopters Hollywood sent in last week are back in the Manhattan airspace today. ABC alerts that "between the hours of 8 a.m. and 5 p.m., there will be movie filming in New York City. As a result, there will be low-flying helicopters over Manhattan. The helicopters will be in the vicinity of the Empire State building, Chrysler Building and Central Park by the reservoir." UPDATE: The copters today are for a commercial. That's one big budget commercial!
