There's been talk for weeks of Boeing developing a fix for the 787 Dreamliner's battery fire troubles. If the aircraft maker has its way, that should soon translate to action. The company's commercial airplane chief, Raymond Conner, tells reporters that the company has a "permanent" fix that would place three layers of protection around the batteries and, theoretically, head off fires and their causes. It sounds like just the ticket -- the challenge will be getting everyone else to feel the same way. American investigators believe the batteries are at fault, but their Japanese counterparts haven't yet ruled out external factors. With this kind of ongoing debate, we're not about to book a 787 to Tokyo for spring break.
