How One Engineer's “Impossible” Propeller Design Made US Fighters 100 MPH Faster?

Описание: How One Engineer's “Impossible” Propeller Design Made US Fighters 100 MPH Faster?
In the summer of 1940, Britain stood on the edge of collapse. German bombers crossed the Channel daily, RAF fighters struggled to climb fast enough, and every minute in the air meant the difference between survival and defeat. What most people don’t know is that the Battle of Britain wasn’t decided by a new airplane or a famous ace pilot—but by three spinning aluminum blades.

This documentary tells the true story of Frank Walker Caldwell, the American engineer whose constant-speed propeller transformed the Supermarine Spitfire from an underpowered interceptor into the aircraft that stopped the Luftwaffe. Dismissed as “too complex” and “too fragile for combat,” Caldwell’s invention gave RAF fighters faster climb rates, higher service ceilings, and longer endurance—exactly what Britain needed when time was running out.

From secret emergency modifications at RAF Hornchurch, to desperate test flights over England, to the engineering revolution that later powered the B-17 Flying Fortress, P-51 Mustang, and P-47 Thunderbolt, this film reveals the hidden technology behind Allied air superiority in World War II.

This is not just a story about airplanes—it’s a story about how engineering, data, and one stubborn inventor helped change the course of history.
