UPDATE | Plane crashes at Kansas airport, killing 4

WICHITA, Kan. (AP) — A small plane lost power after takeoff and crashed into a flight-training building while trying to return to a Kansas airport today, killing four people, injuring five others and igniting a fire that sent up towering plumes of black smoke that could be seen for miles around Wichita.

Three of the dead were inside a flight simulator in the building when the plane crashed into it at the city's Mid-Continent Airport, and the fourth was found on the roof and is believed to be the pilot, Wichita Fire Chief Ronald Blackwell said.

Five others were injured in the crash, and one of those was in serious condition at a hospital, Blackwell said. Officials said only one person was on board the plane and that everyone who was in the building had been accounted for. Identities of the victims were not immediately released.

"We understand that this is a very difficult time, especially for folks who have family members who are working out here and they don't know," Wichita Fire Marshal Brad Crisp said.

The plane, identified as a twin-engine Beechcraft King Air, crashed into a building that FlightSafety International uses to train pilots to fly Cessna planes, company spokesman Steve Phillips said. The FAA said it crashed after losing engine power and trying to return to the airport.
