Apparently one proposal on the table is for a hub screening facility to be established in Port Hardy. Then flights from northern British Columbia would stop over here so that passengers and baggage could be screened. The flights would then resume onto Vancouver. This sounds like a logistically problematic and costly solution.
Stringent aviation security policies put in place for the 2010 Vancouver Winter Olympics may force many small regional airports to cancel flights to the host city during the Games. CBC News reports this is because these smaller airports do not have the equipment necessary to machine screen all passengers and luggage aboard smaller aircraft, and this will be a prerequisite for all aircraft flying into Vancouver.
