Some small details I hadn't seen read before. http://www.huffingtonpost.com/2011/09/26/tsa-airport-screening_n_982097.html "Selected passengers must volunteer to go through a pre-screening process, which may include giving up tons of personal information as well as biometric data that includes fingerprints and iris scans. If they pass, the information will be embedded in the bar code on their boarding pass the next time they travel and they will be directed to a special, faster lane. Passengers will not know in advance if they are eligible for expedited screening," (bolding mine) I don't quite understand this bit. Maybe the info on the BP bar code indicates whether or not the pax is 'eligible' for expedited screening on that particular trip? Still offers nothing for folks like me, as far as I can see. If you're physically unable to assume and hold the position, you're still going to be an involuntary member of the 'grope for life' club, no matter how 'trusted' you are in every other way.
