A small plane crashed on a California freeway on Friday just before 10 a.m., injuring two people, fire officials said.

John Wayne Airport confirmed a Cessna 310 aircraft crashed on the 405 Freeway in Costa Mesa at 9:35 a.m.

The two people injured were the only two passengers on board, a John Wayne Airport spokeswoman told Fox News.

The 1975 Cessna was en route from Palm Springs to John Wayne Airport.

The twin-engine, six-seater aircraft was flying near the airport when it came "just short of the runway," Ian Gregor, a spokesman for the Federal Aviation Administration said. He said the crash occurred under "unknown circumstances."

The airport previously halted arrival traffic, but it has since reopened. Departing flights were not affected. The freeway is closed in both directions near the transit hub.

Orange County Fire Capt. Larry Kurtz said the two people injured were taken to the hospital by a helicopter. The two reportedly suffered non-life-threatening injuries, the airport said.

Videos and photos from witnesses near the scene showed a plume of black smoke billowing into the sky.
