A UTAir Canadair CRJ-200, registration VQ-BGM performing flight UT-832 from Brno (Czech Republic) to Moscow Vnukovo (Russia), was climbing through FL300 when the first officer's windshield cracked.
The crew descended the aircraft to a safe altitude and returned to Brno for a safe landing about 40 minutes later.
Czech's UZPLN reported in their quarterly bulletin the windshield was replaced.
