The 1996 crash, which killed all 230 passengers on board, was, at the time, the second-deadliest airline accident ever in the United States. Several conspiracy theories have emerged following the incident, which speculate that the crash was due to a terrorist strike, a U.S. Navy missile test gone wrong or an onboard bomb.
Courier X links the CIA to the crash, with Burns playing a CIA field manager in the film. Kier plays a former member of the East German secret police, the Stasi, who gets solicited by the CIA. Thomas Gulamerian is directing the film, in his feature debut.
