A Kansas City air show has abruptly ended after a small plane crashed while performing a stunt, killing the pilot, according to AP. Aviation Department spokesman Joe McBride says the pilot couldn't pull out of a maneuver Saturday and crashed the biplane into a grass field at a downtown airport. No spectators were injured. The pilot's name hasn't been released. McBride says the accident is the first fatal crash at the annual Kansas City Aviation Expo Air Show. He says spectators were asked to leave Wheeler Downtown Airport after the crash. Show organizers are holding a news conference later Saturday to discuss details of the incident. Rain initially delayed the start of air demonstrations Saturday morning.
