The brain-trust in D.C. are talking about banning laptops and e-readers in carry-on luggage on flights into the USA. Instead, they'd have to go in checked baggage. That's a dumb idea. The folks at DHS really ought to coordinate with the FAA on this sort of thing.

Airline staff practise what to do: you put the battery into water if you can. Or wet towels. No-one can do that if it's in the hold.
Maybe they should just ban flights altogether.
