This just in: Is the Transportation Security Administration (TSA) getting ready to delay implementing its controversial rule requiring pilots to prove their U.S. citizenship? That's exactly what sources tell AVweb, although we were unable to confirm any details by our deadline Tuesday night. For those of you just joining us, the TSA's new rule on flight training created a mini-storm of protest when it was released last month. [More]Sources tell AVweb that some larger fleet operators have been told by the TSA to continue training foreign nationals already employed by them under previous rules developed by the Department of Justice. In the meantime, the TSA will be sorting out what needs to be done to implement the rule it released last month, even though the agency has had a solid nine months to figure it all out. How long any implementation delay will last is unknown, as are the details. As always, AVweb will continue to monitor and report on developments associated with this controversial rule.
