Overview
- While flying over the North Atlantic the crew of Swiss flight LX9 transmitted squawk 7700 to declare a general onboard emergency and steered the Boeing 777 off its oceanic track toward the Azores.
- The aircraft, a Boeing 777-300ER operating as LX9 from Chicago to Zurich and registered HB-JNF, made a safe landing at Lajes Air Base on Terceira and is now being examined by local ground crews.
- Flight trackers show the jet executed a sharp right turn toward the Azores after the emergency call and the diversion drew priority handling from air traffic because squawk 7700 signals an immediate safety issue.
- Swiss told reporters that cabin crew detected a pungent odor in economy and that several people reported brief symptoms; roughly five passengers and one crew member had precautionary medical checks and the carrier said some return flights were canceled as a replacement aircraft was deployed.
- Lajes Field is regularly used for transatlantic widebody diversions because of its long runways and central location, and authorities say the cause of the emergency remains under investigation before the flight can resume to Zurich.
