WOODBURY - A plane from John F. Kennedy Airport headed to Los Angeles had to make an emergency landing yesterday after it hit a bird moments after takeoff.Passengers say they heard a low groan shortly after takeoff, then felt the plane vibrate and smelled smoke in the cabin. Delta flight 1063 managed to land safely back at JFK Airport. The Federal Aviation Administration (FAA) does not require airports to install avian radar to detect flocks of birds near runways. Instead, it has simply asked airports to step up bird patrols. Experts say there's little pilots can do except be extra careful. Officials at Republic and MacArthur airports on Long Island say bird mitigation is mandatory, 24 hours a day. Full audio recording
