Yes, in another word I am guessing that's what he did. I though it was weird because it was fine when I line him up and closing in. It seem fine until I got to 400 and started firing, then the shifting happen. When I pull back up to go back in for another pass, looking down it was fine, the 3 plane was just flying straight and level with no shifting. On the second dive as I open fire, the shiftin happen again, this time I pulled off and gave up.
