✈️ Thirteen machine guns. Tight combat formations. One of the toughest bombers ever built. So why couldn’t the B-17 Flying Fortress defend itself?

On October 14, 1943, sixty American bombers failed to return from the mission over Germany. Each late-war B-17 carried up to thirteen .50-caliber machine guns — yet German fighters still found ways to break through the defensive fire.

This documentary explores what really happened behind the legendary reputation of the Flying Fortress: blind spots in its defensive coverage, brutal head-on attacks, freezing gun positions, inflated fighter claims, the combat box formation, German cannon and rockets, and the strange YB-40 experiment that tried to solve the problem simply by adding even more guns.

The real breakthrough did not come from another turret. It came from long-range escort fighters such as the P-47 Thunderbolt and P-51 Mustang.

👇 What do you think? Could the B-17 ever have become truly self-defending, or were escort fighters always the only real answer? Share your opinion in the comments.
