Funny, there are lots of carry on x-ray machines in Europe that seem to work just fine 1)With only 2 operators per checkpoint and 2)Without requiring people to remove laptops and other electronic devices from bags. This machine is the Rapiscan.
I haven't checked bags to/from Europe, but I know that I don't see an army of people opening bags due to a 30% false-positive rate. In Munich, they x-rayed people's checked luggage and allowed them to keep it locked. I didn't see anyone being asked to open their luggage after it was x-rayed. Perhaps these are machines that just don't function correctly once they have been imported into the US? Some bizzare 220/110V power conversion problem? Or, perhaps it's because Comrade Daschle's wife is not peddling this particular brand?
