Shackleton WR977
Quoting from the book "Duty Carried Out" ( a history of WR977 ) it says about the Mk3 Phase3 Shacks that " in the late 50's, there was a plan for it to be equipped to carry Skybolt nuclear missiles, as a back-up to the V-bombers, though, perhaps fortunately, this never happened"
Was that really true. The mind boggles !
