ADS-B ground track over the map.
Singapore Airlines flight SQ345, a Boeing 777-300ER registered 9V-SWU, departed Zurich Airport (LSZH) at 09:50 UTC on 11 July 2026 and returned to the same airport at 11:11 UTC, never reaching its scheduled destination. ADS-B data reviewed by SkyMeter shows the aircraft climbed out on a heading of approximately 54 degrees northeast, passing near Dübendorf Air Base, before turning left to a northbound heading of 342 degrees in the vicinity of St Gallen Altenrhein Airport.
Near Friedrichshafen Airport the aircraft executed two successive right turns, swinging first to 95 degrees east and then to 184 degrees south, before a further right turn to 271 degrees westbound near St Gallen Altenrhein. The track shows the aircraft reached a peak of 15,815 feet MSL and then held a prolonged level segment near 15,790 feet on a westbound heading of 270 degrees for well over 20 minutes before descent began in earnest around 11:00 UTC. The steepest descent rate recorded was approximately 3,390 feet per minute as the aircraft tracked a southeasterly heading of roughly 143 degrees.
A stabilized approach on a steady heading of about 155 degrees brought SQ345 back to Zurich, with rollout completing at 11:11 UTC, giving a total flight time of about 81 minutes. The reason for the return was not disclosed. The full flight can be replayed on SkyMeter.
