Factual error: The Royal Canadian Mounted Police are shown checking baggage in the final scenes at the same time that FBI agents are making arrests. The flight landed in Goose Bay, Newfoundland and Labrador, Canada. According to the Criminal Code of Canada, any crime committed during an international flight that ends on Canadian soil is deemed to have been committed in Canada. That being the case, the RCMP as the national police force has full jurisdiction. There is no way the FBI would be involved at that point.
Factual error: Carson says that the explosives were put inside the casket because caskets aren't X-rayed. Even though often times cargo such as the casket are sent by "known shippers", and known shippers check screen the casket, they are still X-rayed by airport security. There are no exceptions to X-raying cargo, even if it was already deemed secure.
