An emergency landing was made at McCarran Airport by an Allegiant Air flight due to smoke in the cockpit of the aircraft. Clark County Department of Aviation spokesman Chris Jones says Flight 394 with 130 passenger on board made the unscheduled stop yesterday afternoon while heading to Grand Junction, Colorado from Los Angeles. Jones says no one was injured. Allegiant spokesman Tyri Squyres described the landing as a precautionary measure and that the plane landed with incident. She says the passengers were boarded on a different aircraft.
