Once about 3 years ago I was out of ammo and tried to ram a Lanc, i dont remember causing any damage but I lost a wing.
Another time I saw a formation of Ju88's low and dove on them with a 109-G10, I dove from about 4-5k lining up on the center of the lead plane. I got a valuable lesson in compression as I was unable to pull out and slammed right in the rear of the Ju88, you would have thought that plane was made of concret. I fluttered down wingless and smoking wreak while the Ju88 no damage.
And just last night I got too close to a B-24 and flew right throught the fusalage from side to side. Heard all kinds of damage noise, only lost an airleon, and as far as I know, no damage to the B-24.
