This Italian Air Force Leonardo C-27J (reg. MM62214) is flying between Pisa San Giusto Ab and the Polish airport of Rzeszów.
Rzeszów is a real hub for the aid, much of it military, that NATO countries (and others) have been delivering to Ukraine for months now.
As has been the case for months now, but it is always worth pointing this out, Hungary, a NATO and EU member, prohibits aircraft carrying military aid to Ukraine from flying over its airspace.
