Actor Harrison Ford was injured Thursday when a vintage World War II training plane he was piloting crash landed on a Mar Vista, California, golf course.

The actor, who was conscious and breathing when rescue crews reached him, was stabilized and taken to a hospital, where he was in fair to moderate condition, authorities said. Sources said he sustained cuts to his head. There was no word on other injuries or what caused the plane to crash. It appeared he was flying solo.

Howard Tabe, an employee at Penmar Golf Course, said, "There was blood all over his face. ... Two very fine doctors were treating him, taking good care of him. I helped put a blanket under his hip."

The plane crashed on the eighth tee at the golf course just west of the airport shortly after takeoff from the Santa Monica Airport, according to Ian Gregor of the Federal Aviation Administration, NBC Los Angeles reported.

An avid flyer of both planes and helicopters, Ford was in a bad crash of a Bell chopper in 1999 Santa Clara, California. In 2008, he told National Geographic, "Well, there was a mechanical failure while we were practicing power recovery autorotations. It was more or less a hard landing. Luckily, I was with another aviation professional and neither of us was hurt — and both of us are still flying."

The National Transportation Safety Board said it was sending an investigator.

It appeared he was flying solo.
