The Boeing B-17 Flying Fortress is a four-engined heavy bomber developed in the 1930s for the United States Army Air Corps. Competing against Douglas and Martin for a contract to build 200 bombers, the Boeing entry outperformed both competitors and exceeded the air corps' performance specifications. Note that if you get your hands on this thing be sure that you're ready to the fact that it's pitch is a bit harder to control. Intructions: VTOL up-down to rotate turret 2. 1 to enable all guns and is only allowed to fire the front gunner. 2 is to enable both front and above gunners to shoot. 3 is to enable all guns including on the ones at the back. I hope you guys enjoy this creation! Peace!
