Pilot reports passenger bit fellow flyer on plane approaching Philadelphia

An unruly passenger apparently bit a fellow flyer on an American Airlines flight as it approached Philadelphia on Sunday, according to the pilot of the plane. The passenger also seemed to become generally combative, with the pilot reporting that the individual on board was "trying to fight everybody" in air traffic control audio reviewed by CBS News. "I don't know ... if he's hallucinating or whatever, but he just bit a passenger and he's trying to fight everybody," the pilot is heard telling a controller in that audio recording, adding, "What a day, huh." The pilot also requested that an emergency medical crew and law enforcement meet the plane upon its arrival at Philadelphia International Airport, "just as a precaution." It's not clear if the unruly passenger was taken into custody. The flight, which left Charlotte, North Carolina, earlier in the morning, landed just before 10 a.m. ET, according to the tracking site FlightAware . The brief exchange between the pilot and controller ended with both of them laughing. When the controller wished the pilot a happy Father's Day, he replied: "I'll be sure to tell my daughters about this one." CBS News reached out to American Airlines for comment but did not immediately hear back. …
