The B17 off the southeast side of Vis is only missing the left nosegun, and the removable guns sometimes carried in the fuselage. Since the plane ditched on the way back from an bombing mission to Vienna, (actually dropped its bombs over Maribor) after it ran out of fuel, it stands to reason that the crew dumped everthing they could to lose weight and get a few more miles. Unfortunately the RAF emergency airfield on the Vis plateau was blocked when the plane wanted to land and the crew did a very good job of setting the plane down in the water.
I can't say for sure, since if I asked I wouldn't want to know the answer, but I probably know who has the missing left nosegun

BTW the nose is at 65M, Tailguns are at 73M and the hole in the fuselage on the right side is just big enough to enter.
