We've had a bit of response from a couple of the other tour possibilities.
If you are at all possibly interested in a tour of the Anchorage ATC tower, Anchorage airport operations center, FedEx Anchorage hub (which processes most of the freight transiting between Asia and North America), or Alaska Airlines passenger or cargo operations, please post your interest ASAP...and please PM me your real name (for security pre-clearance)!
I need to get this info in so the ball can get rolling!
