For more than 20 years, air travelers have had to make sure they bring their liquid toiletries in 3 oz. bottles only, then chug their drinks before passing through airport security — a reaction to foiled terrorist plots that involved liquid explosives. But those days are coming to an end, at least in Europe, where two large airports are installing new 3D Computed Tomography (CT) security scanners that can more accurately detect real threats.Meanwhile, the U.S.'s Transportation Safety Administration (TSA) is "aggressively" adding the new scanners to airports, according to Scientific American, but any change to liquid rules does not appear imminent. Part of the reason for the delay is the patchwork implementation, with only about 255 of the country's 432 airports adding them.
