Friday’s Northwest Airlines incident has people talking about a different type of airport x-ray called a full body scan. In addition to detecting regular weapons, this technology can spot liquid explosives, gels, and PETN (which the suspect in the Christmas-day incident allegedly used). The down-side of the technology: it gives airport screeners - but not other passengers–a very clear look at your body. Passengers can cover their private parts with a metal plate so that the operator can’t see, but the machine will still record the detail.

Privacy advocates call the full body scan a “virtual strip search”. Security advocates call it a life-saving measure.
