A United Airlines Boeing 737-924(ER) aircraft (N69818) traveling from Chicago O’hare (ORD) to Minneapolis (MSP) made an emergency landing in Madison, Wisconsin after an alleged cockpit breach attempt by an unruly passenger. The flight diverted to Madison Regional Airport (MSN) following a level 4 security incident on board, during which the aircraft transmitted squawk code 7500—the internationally recognized emergency signal for hijacking.
Law enforcement aboard the aircraft subdued the subject prior to landing, with additional federal and local authorities responding at Madison’s Dane County Regional Airport. The passenger was detained after reportedly “ranting in Russian” and causing a struggle on the flight. According to FlightAware data, the Boeing 737 landed in Minneapolis early Saturday morning with 147 passengers and six crew members aboard, and no injuries were reported.
A United Airlines spokesperson stated the aircraft “landed safely in Madison … to address a security concern with an unruly passenger.” The incident aligns with reports from FlightRadar24, which notes that squawk code 7500 enables pilots to discreetly contact air traffic control and typically triggers involvement of security forces. Federal authorities are investigating the matter following a tweet citing ATC audio describing multiple attempts by the passenger to breach the cockpit area. The flight’s captain confirmed the skyjacker was seated between passengers during the incident.
