In 1942, the formidable German Luftwaffe owns the skies over occupied Europe. The Allies are eager to challenge their superiority and take the fight to Adolf Hitler’s Reich in whatever way possible. The British Royal Air Force and US Army Air Forces combine operations to bomb the industrial heart of Germany but learn it’s much easier said than done.  

By the spring of 1943, with the Allied invasion of France planned for the following year, Allied air power is tasked with a crucial role: to destroy the road and rail infrastructure of Germany, take out as many of the Luftwaffe planes as possible, and secure control of the air ahead of the landings in Normandy. British and American bombers face off against German fighters and flak batteries in a combat environment like no other. At 25,000 feet, with temperatures 40 degrees below zero, the bomber crews must fight their way deep into enemy territory and back again.

Airmen on both sides will suffer grievous losses—and so will civilians below—as the fight for the skies turns German towns into battlefields on a scale never before seen in warfare.
