2018 Horizon Air Q400 incident

On August 10, 2018, a Horizon Air Bombardier Q400 was stolen from Seattle–Tacoma International Airport in Seattle, Washington. The perpetrator, 29-year-old Richard Russell, was a Horizon Air ground service agent with no piloting experience. After Russell performed an unauthorized takeoff, two McDonnell Douglas F-15 Eagle fighters were scrambled to intercept the aircraft. Sea–Tac air traffic control made radio contact with Russell, the sole occupant, who described himself as a "broken guy, got a few screws loose, I guess." About 1 hour and 15 minutes after takeoff, Russell died by intentionally crashing the aircraft on lightly populated Ketron Island in Puget Sound.
