New 3D scanners at London’s Heathrow Airport allows liquids and laptops to stay in your case

Heathrow will become the first airport in the UK to introduce 3D CT scanners. Passengers at London’s Heathrow Airport could soon pass through security without removing liquids and laptops from hand luggage, under plans to introduce high-tech 3D scanners to help ease delays spent waiting in line.

Heathrow, the UK’s busiest airport with 40 million departing passengers last year, is investing over £50 million ($63 million) in the next-generation CT scanners. By 2022, when the new equipment is expected to be fully rolled out, the time-consuming process of placing liquids and laptops separately in trays could be a thing of the past.

A representative for the airport told CNN that the scanners will allow security officials to see inside bags in much greater detail, allowing them to dissect items in 3D layers. Current technology only uses X-rays, which offer a much more limited vision of contents.
The technology won’t alter the 100ml limit on liquids — an international rule introduced in 2006 following a plot to bomb a transatlantic flight using explosives stored in a drinks bottle.
