This is what battle was like for airmen during World War II

The Air Force today takes a ribbing from the other services for being soft, so it's easy to forget that historically their mission has been one of the most dangerous. This was on display in World War II when Allied aircrews were tasked with bombing Nazi-occupied Germany and Imperial Japan.

In this clip, a World War II Royal Air Force veteran discusses what it was like flying bombers to Berlin through a wall of flak so thick that, as he describes it, it sounded like driving a car through a hailstorm. He also tells of the mission where their bomber was chased down by German fighters and forced to crash land.
