GPS interference forces another Helsinki–Joensuu flight to turn back.

On the morning of 23 August, a domestic Finnair flight from Helsinki to Joensuu was unable to complete its landing because of GPS interference, according to the airline. Flight-tracking data showed that the aircraft circled near Joensuu before returning to Helsinki Airport. Finnair stated that the 21 passengers aboard the diverted flight were rebooked onto an afternoon departure, which was expected to operate normally. The scheduled return service from Joensuu to Helsinki was also cancelled, extending the disruption beyond the incoming aircraft. This was a separate occurrence from the June incident, despite affecting the same route and destination. The report documented a concrete operational consequence of navigation interference: an aborted landing, a return to the departure airport and a cancelled onward service. It did not specify the duration of the interference, distinguish technically between jamming and spoofing, or identify the transmitter responsible for this particular event.
