Even at 100% volume for the "things hitting your plane" slider, The hit sounds are super weak and I am unable to tell a 303 from a 20mm. Just a "pew" and something falls off. Or doesn't. What plane hit me? Various descriptions from actual pilots said they could feel and hear the hits, even over the sound of their engines. Since we can't feel hits in the game, could you make the hit sounds a lot louder, please?
And the damage sound when a part falls off is even quieter.
