At one point the diplomat steals a Beechcraft Model 18 from an alleged Indian airport. All the aircraft on the flightline are American models wearing U.S. N-registrations and the airport is obviously in Southern California due to the mountains and eucalyptus trees visible. The Beech he commandeers is a civilianized ex-USAAF AT-11 Kansan with the former bombardier glazed nose faired over with metal. Once airborne, the Beech shown is a round-nosed C-45 model. When the actor leaves the cockpit to bail out, another sideview of the C-45 shows a pilot still in the pilot's position.
It is inconceivable that a corpse with three bullet holes in its face would be considered a suicide.
