As you may or may not have heard, this morning Scotland Yard announced 21 people were arrested in connection with a supposed terrorist plot to use liquid explosives onboard. The result was obviously arduous for travelers who suffered suspended flights and long lines -- certainly a better fate than the possible alternative -- but the collateral inconveniences were also rather interesting. Authorities banned bringing aboard liquids, gels, or lotions (aside from medicines and sustenance for small children), as well as effectively scrapping travelers' ability to carry on laptops, cameras, or cellphones until further notice. Pretty severe for those looking to get some work done or pass time on their flight, but anyone lucky enough to get on a plane in England today is probably more relieved than irritated. Just be sure these guys don't lose your luggage, ok?
Update: For clarification, as far as we know gadgets are still allowed on American flights -- this precedent pertains primarily only to British and possibly some European flights.
Update 2: Looks like things are loosening up a bit, and passengers can start carrying on a bit of baggage themselves. For more info peep the Beeb. Thanks Stewart.
