How the boss of London City plans to revolutionise airport security

Baggage scanners at departure could soon be consigned to the scrap heap, according to the chief executive of London City Airport. Robert Sinclair, the New Zealand executive in charge at London City, predicts that technology will let passengers "walk through a security lane carrying a bag behind you, and being scanned as you walk through." The idea would turn airport security at departure into an experience more like passing through customs than the current arduous ordeal of unpacking bags and emptying pockets as goods are passed through scanners individually. Sinclair’s comments come as London City trials state-of-the-art baggage scanners on one of its security lanes that mean passengers no longer have to remove liquids, tablets and laptops from their bags.
