Oh, good grief. Physics.org has just revealed that laptops can suddenly explode, posing a substantial risk when used in flight (and elsewhere). Apparently, the problem lies with faulty laptop batteries...Comforting information to read on your laptop--which seems to be located in a rather precarious location in the event of a explosion. Unfortunately, I'm sure if a laptop can blow up on accident, it can certainly blow up if some idiot takes it into his head to detonate it. Sigh. I wonder how long it'll be before laptops are completely banned on planes?
