suraj.sun writes in with a story about the spread of full body scanners. It reads in part:"Passengers at airports across Australia will be forced to undergo full-body scans or be banned from flying under new laws to be introduced into Federal Parliament this week. In a radical $28 million security overhaul, the scanners will be installed at all international airports from July and follows trials at Sydney and Melbourne in August and September last year. The Government is touting the technology as the most advanced available, with the equipment able to detect metallic and non-metallic items beneath clothing. It's also keen to allay concerns raised on travel online forums that passengers would appear nude on security screens as they had when similar scanners were introduced at U.S. airports. The technology will show passengers on a screen as stick figures of neither sex."
