MMMMH! BOOBIES! Bouncy, bouncy, boobies.... Wait you posted something?
Seriously, looking at the film, you did not get a clean shot. You hit the radiator, engine, left wing, and behind the pilot. Half second of .50 burst that spread out you were lucky to get the engine and radiator.
109 engines and radiators are made of tissue paper and glass with this damage model. You could sneeze and cause an oil leak, or fart loud enough and the radiator will blow it's top. I love 109's cause if I look at them hard enough they cr@p oil, and pi$$ glycol.
