Overview
- United Airlines Flight 2092 from Chicago to New York diverted to Pittsburgh on Saturday after the crew reported a suspicious one‑per‑second beeping and declared an in‑flight emergency using transponder code 7700.
- The Boeing 737 landed safely and 159 passengers and six crew evacuated via emergency slides with no injuries reported.
- FBI special agents, bomb technicians, and the Allegheny County Police bomb squad with K‑9s searched the aircraft, passengers, and luggage and reported negative results, and authorities later cleared the scene.
- United rebooked travelers on another aircraft to LaGuardia later that day, while officials said the federal inquiry into the reported threat remained active.
- The 7700 code tells air traffic control a general emergency is in progress and triggers priority landing and security protocols, which in this case followed cockpit audio and data messages that flagged a possible bomb; a separate United flight in Denver faced a reported threat the next day and departed hours later after screening.
