80 years ago Wing Commander Joseph Watts was killed when his RAF Hampden Bomber crashed, as it returned from a bombing raid in Occupied Europe. He left behind a daughter, and also an unborn son. John Watts, born 8 months later, would never meet his father. But recently he discovered that at the RAF Museum at Cosford, they have one of the very few surviving Hampdens. And this one is from the very squadron his father flew in. In this poignant documentary, John sees the plane for the very first time.
