Cargo plane fire prompts SFO evacuation

About 100 workers had to evacuate a building at San Francisco International Airport Saturday night because of thick smoke from a nearby cargo plane that caught fire while preparing to take off, an airport official said.

Only two pilots were onboard at time and one was sent to the hospital with minor injuries, airport Duty Manager Lily Wang said.

The cockpit of the cargo plane caught fire around 10:15 p.m., said Wang.

It was parked at Plot No. 11 in a remote area of the airport, Federal Administration Aviation spokesman Bruce Nelson said.

Workers at an air mail facility were evacuated because 'the smoke was so thick," said Wang.

She said no other injuries were reported and the cause is still under investigation.

The plane will be unusable for "a while," she said.
