During the mission

I had to follow the instructions of my superiors
I was told to run around between the dorsal turret and the tail gun to hit the German fighters and I was told which direction the German planes were coming from using the clockwise direction e.g. 12 o'clock 6 o'clock etc. If a wing of my own plane was shot my superior would tell me to cut the fuel line to that wing (the fuel line switch to be closed was flashing gold).
