Myerson's motive was to silence anyone connected to the money smuggling operation. The priest and Vera Franklin were both involved in helping smuggle stolen money out of the country aboard the aircraft. Myerson needed to prevent them from revealing his involvement in the criminal scheme, so he murdered them to protect himself from exposure.

Foreshadowing: The letter received before takeoff mentions a sequence of murders tied to criminal activity, hinting at the killer's connection to the smuggling ring.

Karen White, a flight attendant, was revealed as the true mastermind behind the smuggling operation. She had planted the stolen money in someone else's bag, not in Vera Franklin's bag as everyone assumed. When Franklin's bag was dropped before takeoff, it contained no money, which initially cleared her of suspicion. Karen was the one who orchestrated the entire scheme and framed others for the crime.

Foreshadowing: The investigation focuses on Vera Franklin's bag as the money's location, but the reveal shows someone else controlled the operation.

The priest aboard the flight was revealed to be an imposter and a known thief. Detective Myerson targeted him because the priest was involved in the money smuggling operation with Paul Barons and Vera Franklin. Myerson needed to silence the priest to keep his own involvement in the criminal scheme hidden.

Foreshadowing: The initial investigation treats the priest as a suspect, with Myerson personally hunting him before finding him dead in the dumbwaiter.

Vera Franklin, the flight attendant, was murdered because she was directly involved in the money smuggling operation. She was helping move illicit funds out of the country aboard the aircraft alongside the priest and Paul Barons. Myerson killed her to prevent her from revealing the details of the smuggling ring and his connection to it.

Foreshadowing: The second murder occurs after the letter's contents are revealed to passengers, showing the killer is eliminating those tied to the criminal operation.

Otto Gruenwaldt blamed Dr. Kenyon Walker for failing to save his dying wife. This personal grievance created tension between the two passengers during the flight. When Gruenwaldt suffered a heart attack, Dr. Walker administered a life-saving drug, but Captain Larkin demanded the syringe as potential evidence, creating further conflict.

Foreshadowing: Gruenwaldt's confrontation with Dr. Walker early in the flight establishes the theme of passengers harboring grudges against one another.

Captain Larkin distracted Myerson by releasing the oxygen masks, then lunged for the gun. A violent struggle ensued during which Barons was killed and the cabin caught fire. The passengers then banded together to extinguish the flames, bringing the immediate crisis to an end.

Foreshadowing: The letter's promise of murders creates rising tension that builds toward this violent climax.

Vera Franklin's bag contained no money because Karen White, the true smuggler, had planted the cash elsewhere. When Franklin's bag was dropped before takeoff, it appeared empty, which initially cleared her of suspicion. The real guilty party had hidden the money in a different location, framing Franklin as the smuggler.

Foreshadowing: Investigators focus on Franklin's bag as the money's location, making the empty bag a key red herring in the investigation.

The letter received by safety official Donaldson before takeoff served as a ominous warning that a sequence of murders would occur on Flight 502 before it landed. While the bomb threat in the lounge turned out to be a prank by Millard Kensington, the letter's warning proved dreadfully accurate as murders did indeed occur aboard the aircraft.

Foreshadowing: The letter establishes the film's premise and creates tension from the very beginning, with the murders fulfilling its dark prophecy.
