Overview
- A United Airlines Boeing 737 traveling from Chicago to Minneapolis diverted to Dane County Regional Airport on Friday night after crew reported a security concern; flight-tracking data show the plane landed in Madison about 90 minutes after takeoff.
- Passengers and air-traffic control audio say off-duty law enforcement and crew restrained a man who allegedly made multiple attempts to reach the flight deck before the aircraft turned to Madison.
- Local deputies removed the individual on landing and the FBI’s Milwaukee office was notified; United confirmed no injuries among the 147 passengers and six crew and the flight later continued to Minneapolis.
- Some media and witness reports said the man was speaking Russian and that the flight may have signaled a high-severity code, but officials have not publicly confirmed the passenger’s language, motive, squawk 7500 use, or a formal Level‑4 threat classification.
- The FAA and FBI will investigate the case, which comes as airlines report hundreds of unruly-passenger incidents this year and could result in civil fines or criminal charges if authorities find violations.
