GIANTS IN SCREENING


EVOLVING SECURITY SCREENING: TRENDS IN


Since passenger pre-board security screening was introduced, airports have experienced a dramatic expansion of space requirements to accommodate screening equipment, slower processes, and ongoing increases in peak- hour volumes of passengers and bags. A key cause of this expansion is the need for focussed threat detection – ranging from the identification of sharp objects that could potentially be used as on-board threats to the current emphasis on the detection of explosive devices. As well, passenger behaviour has also changed significantly during the same period, which has also affected screening practices and equipment needs. In the 1970s, passengers boarded with books and magazines to pass the time. Today they board with an increasing array of electronic gear: tablets, smart phones, e-readers, notebooks, portable game consoles and more – each of which represent a new challenge to the art of detecting potential threats to aviation. Solomon Wong discusses the resulting developments in checkpoint design.
