A pilot has ejected moments before his F-16 fighter jet crashed into a warehouse near an air base in California.
The pilot was not hurt, and there were no immediate reports of injuries on the ground.
The cause of the crash is under investigation.
Television news showed a large hole in the roof and sprinklers on inside the building about 65 miles east of Los Angeles.
Daniel Gallegos, a warehouse worker, said he is used to hearing the sound of planes coming and going, but the noise just before the crash was deafening.
He said: ‘Next thing I know I just hear this explosion and turn around to the back of the building, and I just seen a burst of flames and just the ceiling started falling through every part of the building.
‘I turned around, and my co-worker just told me to get, so I just made a run for it.’
Mr Gallegos said he believed one of his co-workers was struck by something — possibly a falling fire sprinkler — but was not seriously hurt.
The crash happened as the pilot was landing following a routine training mission.
