Samuel "Sam" McKeon (portrayed by Tom Butler) is a minor character in Snakes on a Plane. He is the captain of flight Hulu 1-2-1.
When Hulu 1-2-1 departs from Honolulu, Hawaii, no one is aware that gangster Eddie Kim has planted a large number of venomous snakes aboard in order to eliminate Sean Jones, who witnessed him commit a murder. The snakes are driven crazy by a special pheromone sprayed upon the leis that the passengers are wearing. A short time into the flight, the snakes are released from their crate in the cargo hold and slither freely throughout the plane.
After the aircraft's avionic board goes out, Captain McKeon goes to inspect the damage. Inside the crawlspace beneath the cockpit, the captain is attacked by an anaconda that bites his neck. The snake's venom triggers a heart attack, killing McKeon instantly.
