I suspect he is talking about the Pilot position which in the gunsight selection window is the 6th position(first in the list for the Ki-67). If that bomber had a gunsight in the pilot's position in real life, then there would be something to see. Ever try to change out the gunsight on the wirble, same problem he is having here. Guess this wish should be to mask any bomber position from the gunsight selection app that does not represent a real gunsight position a player will see a reticle and man a gun...
