A Montenegro Airlines Fokker 100, registration 4O-AOT performing flight YM-500 from Podgorica (Montenegro) to Vienna (Austria), was enroute at FL340 near Belgrade (Serbia) about 145nm north of Podgorica, when the crew decided to return to Podgorica due to a failed windshield heating and temperatures and weather conditions ahead and at Vienna. The aircraft landed safely back about one hour after departure.
