Captain Adams and Chief Pringle
Apparently the Captain and Chief had relatives in America who worked for an airline! I just started watching Andrew Stone's previous film "Cry Terror!" and in the opening scene noticed that the letter address to the President of 20th Century Airlines was to "Robert Adams" (same name as the Captain) though he later on the phone identified himself as "Roger Adams". Then he asks for his security chief, Dan Pringle.
I guess Stone must have had friends with those names to reuse them again in his next film!
