Overview
- United Flight 2092, which diverted Saturday to Pittsburgh, evacuated 159 passengers via slides after the crew heard steady beeps and treated the noise as a possible bomb.
- Allegheny County bomb squad teams and FBI technicians swept the jet, passengers, and bags with negative results, and travelers were rebooked to reach LaGuardia after long delays.
- The Boeing 737 sent the 7700 code, which signals a general emergency to air traffic control and prompts priority landing and rapid response on the ground.
- In a separate case Sunday night, United Flight 2408 from Denver to Dulles was held for a security screening with passengers disembarking and the plane departing more than five hours late after no explosive was found.
- Investigations continue as airlines and law enforcement take beeping alerts and other reports seriously, a posture that is producing diversions, tarmac screenings, and major delays even when searches find nothing.
