In the attached image, from your film, you will see a view looking back from in front of Max (the Brewster). Your plane is in the background, and you see your fire hitting Max on the wing. From this point, you continued to hit Max's plane across the entire wing and fuselage. I did not bother counting the hits, but it was numerous.
Once you did that, your plane was damaged beyond salvation and your tail broke off when you tried to pull up from the stall you suffered almost immediately after this.
This is the result of the 'killshooter' flag in the arena. It is also fair to note, not all arenas have this flag set. The Training arena does not have this flag set.
