Helicopter Crashes Into Raytheon Building, Erupts Into Flames

A helicopter burst into flames after crashing into office and laboratory building at Raytheon aerospace development complex on the 2000 block of E. El Segundo Boulevard shortly after 9:30 a.m. on Sunday morning, reports Reuters. Eyewitness reported that the Sikorsky S-58ET helicopter "erupted into a ball of flames when it crashed," reports KTLA.

The plane was reportedly lifting a large air-conditioning unit from a low rise building "when the pilot lost control, and the helicopter crashed into the building, setting two floors on fire," reports KTLA.

According to the Federal Aviation Administration, the pilot survived and was pulled from the aircraft by people on the ground before it burst into flames, notes NBC Local. The pilot was taken to a local hospital with serious injuries. No other injuries have been reported at this time. Heavy damage is reported on location, authorities say
