I am siding with Distind on this one. 50 million worth of cut diamonds is worth the extra expense of using a private jet from a private airport or private secured section of this airport in question, or even to use a helicopter directly from the roof of the shipment consolidation building (it was going to Switzerland from Belgium, within fuel range for most larger civvy helis). By using private aircraft from secureable private take off locations, armed security and video monitoring can be increased, and there is much less risk to civilians if armed security agents need to defend the shipment with gunfire.
