Nobody was on the plane, but this doesn’t look good for Boeing’s jumbo jet of the future. The New York Times says:

Boeing said it was aware of the problem, but the airport, the airline and Boeing have not identified the cause of the fire.

The incident took place about two months after the innovative 787 Dreamliners returned to the skies after being grounded for four months because of hazards with a new type of battery. One of the lithium-ion batteries caught fire on a 787 parked at a Boston airport on Jan. 9, and another began smoking in midflight a week later, forcing the 787 to make an emergency landing in Japan. In the Boston incident, the fire took longer to extinguish.

The visible damage from the fire was nowhere near the part of the plane where the batteries would be, but still: A lot of Boeing employees are not going to sleep well this weekend.
