An incident aboard a parked 787 Dreamliner at London's Heathrow Airport does not appear to be related to the batteries on the aircraft. Boeing spokesman Marc Birtel said the aircraft manufacturer "is working to fully understand and address" the London 787 issue. Ascend Director of Safety Paul Hayes noted that Boeing will be anxious for the cause and origin of the fire to be released promptly. "Boeing will want the final bulletin out as soon as possible to stop all the waffle and provide certainty," Hayes said. "Given the public interest in it I'd expect the AAIB to get it out quickly, probably in the next couple of days."
