John Watts never knew his father. He was conceived days before his father, Wing Commander Joseph Watts, was killed on a bombing mission over occupied Europe. He left behind a daughter, and also an unborn son. But, recently John discovered that at the RAF Museum at Cosford, they have one of the very few surviving Hampdens which is being restored. The plane is from the very squadron his father flew in. Dan accompanied John to the museum for the emotional visit which he hoped would bring closure after 80 years of pain.
