Answer: CT scanners (sort of).
Working in partnership with American Airlines, the Transportation Security Administration (TSA) hopes to begin using the machine in late July at the John F. Kennedy Airport in New York, The Verge reports. This new luggage scanner uses the same technology as a medical CT scanner to produce a 3-D image of the inside of a bag. According to TSA Administrator David Pekoske, the CT scanner is not only more effective than traditional X-ray technologies but could also make security checkpoints easier for passengers.
This is because it can detect a wider range of explosives, particularly lower weight ones. Passengers would therefore no longer be required to remove items like liquids, aerosols and laptops from their bags. “They’re just much better at detection, so you really get better security faster, essentially,” Pekoske told CBS News.
