(…unless we’re selected for ‘pre-check’ that is)
After spending millions of dollars testing four different scanning devices that would allow airline passengers to keep their shoes on at security checkpoints, the United States government has decided for now that travelers must continue to remove their footwear, by far the leading source of frustration and delays at the airport.
The Transportation Security Administration said it had rejected all four devices because they failed to adequately detect explosives and metal weapons during tests at various airports. One of the scanners is now used in airports in 18 countries.
The machines detect explosives in shoes just as well as putting shoes through an x-ray machines. But don’t detect some things that x-raying the shoes also fails to detect.
Curiously, alternatives to the shoe carnival seem to be held to a much higher standard than the rest of the things actually deployed by TSA — unreliable nude-o-scopes and even less reliable screeners.
