"AN X-RAY machine that sees through air passengers� clothes has been deployed by security staff at London�s Heathrow airport for the first time.
The device at Terminal 4 produces a �naked� image of passengers by bouncing X-rays off their skin, enabling staff instantly to spot any hidden weapons or explosives.

But the graphic nature of the black and white images it generates � including revealing outlines of men and women � has raised concerns about privacy both among travellers and aviation authorities.
In America, transport officials are refusing to deploy the device until it can be further refined to �mask� passengers� modesty. "
