SAN FRANCISCO (KCBS) -- Federal and local officials will meet at San Francisco International Airport Sunday to find out what caused Airborne Express cargo plane to burst into flames Saturday night.
The Boeing 767 was parked in a hangar near a building where mail is processed when it caught fire just after 10 p.m.
According to Duty Manager Lilly Wang, people began pointing to heavy black smoke coming out of an area behind the cockpit.
There were two crew members on the aircraft -- which is the pilot and the co-pilot -- and they escaped without any injury," said Wang.
Neither was injured, but the co-pilot did go to the hospital.
The fire threw billows of black smoke into the air, forcing more than 100 people in a nearby building to evacuate.
The intense flames also caused serious damage to the plane.
"You can actually see through the top of the aircraft. It spread all the way through," said Wang.
The fire forced the temporarily closure of roads into the airport for about ten minutes while emergency crews responded to the scene. But landings and takeoffs of passenger airplanes were not affected by the incident.
It took two hours for firefighters to extinguish the blaze.
