TSA Limits Lithium Batteries on Airplanes
yali writes "The U.S. Transportation and Security Administration has issued new rules limiting travel with lithium batteries. As of January 1, no spare lithium batteries are allowed in checked luggage. Batteries carried in the cabin are subject to limitations on per-battery and total lithium content, and spare batteries must have the terminals covered. If you're returning home from the holidays with new toys, be sure to check out the new restrictions before you pack."
I recall a rather nasty home-defense weapon that a friend of mine had for his wife to use ( they were in a rather rural area with slow police response ). It was a short-barrel .44 revolver - light, easy to use, won't jam - with a load that looked like a miniature shotgun shell. It had a bunch of pellets about 1 mm in diameter. He said that it could rip a person apart at close range, but could not penetrate 2 sheets of drywall.
Seen at London City airport in London by security - a vending machine selling pre-stamped mailers and a post collection point. Such a small thing to organise but how many passengers feel happier not having to 'lose' stuff at security.
See my journal, I write things there
