A small jet crashed Sunday at a Southern California airport killing two people on board, according to reports. Following the incident, the airport has been shut for 24 hours.

The L-39 jet trainer went down soon after it took off from the Apple Valley Airport in San Bernardino County, about 70 miles northeast of Los Angeles, the Associated Press (AP) reported. No casualties were reported on the ground.

Fire Marshal Jason Nailon said a witness reported that the plane’s engine caught fire as it was taxiing down the runway, according to the AP. Officials are yet to identify the deceased.

The Federal Aviation Administration (FAA) and the National Transportation Safety Board have launched an investigation into the crash. An FAA spokesman told CBS News that the jet went down “in a fireball.”

The L-39 is reportedly a two-seat, high-performance jet trainer aircraft made in Czechoslovakia.
