What's new here? I recall some 25 years ago - even on a domestic flight - the security people told me they needed to see the scanner I was taking with me "doing something". I switched it on, it lit-up and hissed and that satisfied them. In retrospect, I don't really understand what reinstating this elementary test would prove. You can rip the guts out of such a device and use a 3v lithium coin cell to drive a tiny board whose only purpose is to briefly light the display and generate a hissing noise to the loudspeaker. You then have all the rest of the inside of the case for your explosive etc. You don't have to be a genius to figure out a ruse like this. Seems clear to me this reinstated policy will do nothing to improve airline security and will only result in more stress and delays - unless of course the matter has been misreported in the media. Anyone know anything about this?
