Seattle Boeing Co. was able to reopen its factory for 737 and 757 passenger jets Friday morning, but was still unsure when it would be able to use Boeing Field to test and deliver airplanes after the earthquake that rocked the region Wednesday.
The 6.8-magnitude quake closed all but half a runway at Boeing Field, which had cracks in runways and taxi ways and damage to the airport terminal. Boeing's test and delivery center for its smaller jets is located at the airport, while its corporate headquarters, military aircraft plant and several research and development facilities are across the street.
Officials with King County, which runs the airport, have said it could be four to six weeks before the airport is fully functioning.
That closure leaves 16 airplanes stranded at the airport south of Seattle, Boeing spokesman L. Craig Martin said.
Boeing has operations in Wichita.
