ONTARIO, Calif. (AP) — A United Airlines flight from Los Angeles to Washington, D.C., made a quick emergency landing at another Southern California airport Thursday morning after passengers reported a burning smell on board. United Flight 1181 from Los Angeles International Airport to Dulles International Airport landed safely at Ontario International Airport, about 40 miles east of downtown Los Angeles, just before 9 a.m. There were no reports of injuries among the 199 passengers and seven crew members, United spokeswoman Mary Ryan said. About half an hour into the flight the pilot declared an emergency, and within about five minutes the plane was on the ground, according to Harold Johnson, an Ontario airport spokesman. "They put the pedal to the metal and got us here pretty quickly," said passenger Jim Clarke.
