Hi Richard,
The owner of the flight school I spoke to yesterday is very, very, tight with the FAA and couldn't get an answer after 1.5 hours on the phone to the FSDO, and not even after being passed to the head TSA person in the region. Apparently the rules and regs are not being transmitted west of the Mississippi
. Round here they all appear to be doing what is going to cause them least problems with the authorities if they get it wrong. What people don't realise is that even US citizens will have to produce documentation to prove they are US citizens, and I know plenty of people who don't have that documentation to hand.
