We have the details on a plane crash that killed three Tesla executives in California. The story inside.

Three Tesla employees were killed when their airplane crashed in heavy fog shortly after take-off.  The plane, a twin-engined Cessna 310 owned by Tesla senior engineer Doug Bourn, collided with power lines 60- to 100-feet in the air before hitting the ground.

Tesla CEO Elon Musk and CTO J.B. Straubel were not on board.

An explosion was heard when the plane crashed into a residential neighborhood, but it is unclear if the Cessna hit the ground intact, or broke up after smashing into power lines.  Firefighters successfully battled flames caused by the wreckage, later reporting there were no other injuries or deaths tied to the incident.

In a statement, Musk said that the company has requested authorities to hold off on releasing the identites of the deceased to the public until families were properly notified, a standard practice.

"Our thoughts and prayers are with [the family]. Tesla is a small, tightly-knit company, and this is a tragic day for us," Musk said.
