Looks like the days of the laptop (and perhaps other gizmos) on airlines are numbered. First, Virgin becomes the third airline [CNET news] to place restrictions on Apple and Dell laptops, allowing them on planes only if the battery [Virgin site] has been removed, wrapped and stored in carry-on luggage. (Qantas and Korean Air have already placed restrictions [CNET news].) You can use the laptops from a power source in some instances on these airlines.
But this story doesn’t seem to be going away. A person posted a story on the Awful Forums (the account is also posted on Gizmodo.) alleging that an “IBM laptop” (presumably a ThinkPad, now owned by Lenovo) caught fire on a United plane boarding at Los Angeles airport. The passenger reportedly ran up the gangway from the plane dropping his laptop on the floor of the departure lounge where “the thing immediately flares up like a giant firework for about 15 seconds, then catches fire”. The owner, apparently, had checked his battery against a list of those of these being recalled, and it wasn’t on it.
Notebook Review has this to say: “An incident like this makes you wonder how long it is before in flight laptop use when running on batteries is just banned altogether. Which would be a black eye to both the airline and notebook industry.” I’d tend to agree.
