Transcript for Dreamliner Passengers Evacuated After Fuel Leak
And the big scare for passengers on the Boeing dreamliner. They were about to take off when they saw something gushing from the wing. Jim Avila shows us. Reporter: We're about to take off from Bangkok when they saw this outside their window, fuel pouring out of a wing on the dreamliner right onto the runway. The 285 passengers were evacuated without incident. But for Boeing and its plane of the future dubbed the dreamliner for all of its creature comforts and fuel economy, reliability remains a problem. You know, the only problem with the 787 is that it's a new airplane and new airplanes get a lot of attention especially ones that are so uniquely built. Reporter: In Japan a 787 traveling from Tokyo to Boston was forced to turn around over Canada after a fuel pump problem was detected. A week before that, a fire on an empty dreamliner forced heathrow to close both of its runways. The dreamliner was grounded for three months last year after concerns about overheating lithium battery, a nippon airways flight as forced to make an emergency landing and evacuation after in-flight alarms located a battery fault. Panic on this Japanese airliner when smoke in the cabin forced the evacuation chutes to open and passengers to clammer for the exits. As for this latest runway fuel spill, Boeing told ABC news, it is working with Norwegian on this issue and the passengers were never in danger. They said the pilots would have seen a cockpit warning before taking off with that much fuel leaking. Most of these issues have been minor but this being the age of youtube not a good time for such a rough launch for such an important plane.
