[HANG THE EXPENSE]

Putting a cannon in the nose of 666(fired by the pilot) made for a nasty little surprise to those that pressed head on attacks on that bird.We have searched for pictures for years and no luck.

I was in the Army and this was one of their nasty surprises called a gun truck.

Armorers who upgunned Old 666, installed a fixed, forward-firing .50 caliber aircraft machine gun for the pilot, Jay Zeamer, to shoot. Old 666 carried 19 .50 machine guns (six more than the other B-17s). The .50 caliber is NOT a cannon — it is smaller than the 20mm machine gun.
