About this programme

1/10. Chris Hollins invites descendants of members of 617 Squadron, the `Dambusters', to learn the exact parts their ancestors played in Operation Chastise in 1943. Erica is the great-granddaughter of Barnes Wallis, the inventor of the bouncing bomb, Chloe is the great-great-niece of Guy Gibson, the officer who led the raid, and Felix is the great-grandson of Edward Cuthbert Johnson, the man who aimed the missile at the Eder Dam.
