A twin-engine plane crashed into a California neighborhood on Monday, killing the pilot and a UPS driver.

Surveillance video obtained by local news station KGTV shows the plane, Cessna C340, appear to drop out of the sky before exploding on a street in Santee, California, a suburb of San Diego.

Witnesses told NBC San Diego that the plane crashed on a residential street and hit a UPS truck before slamming into two homes.

The pilot of the plane was Sugata Das, a cardiologist at Yuma Regional Medical Center in Arizona who lived in San Diego, friends told NBC San Diego.

The UPS driver has not been publicly identified.

Santee Deputy Fire Chief Justin Matsushita told NBC News that two people were injured in the crash, multiple cars caught fire, and power was cut to 10 homes.

Matsushita said it remains unclear if anyone other than the pilot was on the plane.

What caused the crash is also unknown, but audio obtained by NBC San Diego shows an air traffic controller telling Das that his plane was too low.

The National Transportation Safety Board is investigating the crash.
