Effective tomorrow, new FAA rules take effect which restrict how and if lithium ion batteries may be taken on a flight. Rechargeable lithium ion batteries are commonly used in cell phones, notebook computers, digital still cameras and you guessed it, video cameras.
While the goal of the new safety restrictions is laudable, they're also unevenly applied which casts doubt on any safety benefit. The restrictions for passengers are fairly clear but as the folks at TechThoughts.org point out, "The problem I have with it is, in the belly of the plane, there’s cargo containers that are filled by shipping companies. There’s no regulation that says you couldn’t send 10 of those 160 WH batteries in one box with a cargo carrier- who then puts it on the same damm plane you sit in."
