A Hawaii-bound jetliner returned safely to Los Angeles on Monday after a cockpit light suggested a fuel valve was open.
Hawaiian Airlines Flight 3 was about half an hour over the Pacific Ocean, on its way from Los Angeles International Airport to Honolulu, when a warning light on the Airbus A330 illuminated.
An airline spokeswoman said mechanics checked the plane after it landed and found that the valve was closed.
The flight, with 290 passengers and 10 crewmembers on board, took off shortly before 1 p.m. The pilot declared an emergency.
Instead of returning immediately, the plane circled off the California coast to burn fuel before landing.
Just after 4:30 p.m., it took off a second time, headed for Honolulu again.
