Just found this interesting article via TheAviationist about a midair collision between a Russian Su-27 and a norwegian P3B Orion. After two successful but very close passes the young Flankerpilot hit one of the Orion’s propellors, causing damage to both planes. The Orion managed to get back safely on 3 engines, escorted by 2 F-16. Also the Flanker got back with a damaged tail and later got a kill marking behind the canopy.
