A passenger jet with three people on board has crashed into a hangar at an airport in California.
An investigation has begun into whether and how the pilot lost control during an engine test.
Local media reported that the engine was being checked while the plane's tyres were on chocks.
It is thought that the jet somehow came off the chocks, and it crashed into a hangar.
Nobody was injured.
