(CNN)The long investigation surrounding a mysterious battery fire that made so much trouble for Boeing's 787 Dreamliner is closed. The National Transportation Safety Board report -- released December 1 -- comes nearly two years after burning and smoking batteries grounded all 50 of the world's most advanced airliners flying at the time. When you pick apart the 110-page document, it reveals how any new piece of equipment can pose dangerous problems, even a noncritical piece of equipment like batteries. In this situation, the battery created one of the worst threats possible: an onboard fire. From a broader perspective, the investigation reminds us of the heavy responsibilities shared by the world's aviation regulators and aircraft makers. The battery problems struck Boeing shortly after it had rolled out what was then a new model aircraft, with some of the most sophisticated technology available.
