Seeing aircraft through the P-38G gunsight is very hard for me. I wish the P-38G had less hindered transparency through the various layers between me and the plane I'm trying to shoot. I would like the fly the P-38G, but I just can't see well enough through its gunsight to be effective with it.
There might be other planes that suffer from very dim views through the gunsight (the TBM's is also pretty hard to see through).
