WWII pilot in an oxygen mask beneath a bomber formation on the upper arm

A Second World War airman in his flying goggles and oxygen mask, with a formation of bombers passing overhead and parachutes drifting down behind them. It's a piece about the young men who flew those missions.

The bombers fill the top of the shoulder, the pilot runs down the back of the upper arm, and a bank of cloud carries the piece down into the elbow.
