A Hellenic Air Force Embraer EMB-145 AEW&C (reg. 729 – callsign OURAN31) is returning to Elefsis AB base after a mission, most likely over the North Aegean.
The aircraft took off at 09:53 CET from Volos AB and is currently returning to Elefsis.
In less than two hours of flight (during which the ADS-B transponder was switched off) the aircraft could not have gone much further north.
