[the lancaster kicks ass]

the dialog is all one man talking, and he is a spitfire pilot, "boy" in this case, refers to the man he is talking to, and it's supposed to be funny, because he is a spitfire pilot, and is claiming to have sunk the tirpitz........

I've changed it yesterday (as you probably nioticed) after watching one of my WWII archive shows called Kamikaze In Color. But I had 2 bottles of 0,5l vodka before, so I'm still a bit under steam and dunno if it's translated correctly. But the meaning is already there, IMO.
