In these minutes (18:20 CET) we’re tracking a German Air Force Eurofighter EF-2000A (reg. 30+02) is back to Germany after a Combat Air patrol mission performed over eastern Poland, near Russian enclave of Kaliningrad.
Probably there are two aircrafts in flight but only one of them has ADS-B transponder switched on.
The aircraft has departed at 16:31 CET from Rostock AB, home of Jagdgeschwader 73 of the German Air Force.
