| Description | In his letter of 1 November 1973 Blackett explains: "I am writing up a good deal about my activities during the war, particularly certain parts of operational research and I felt I would like to mention the Mk 14 Bomb Sight as this was conceived and designed by a young colleague of Birkbeck College and was a great success". Later he says: "I am only interested in what we did in 1943…" but this would appear to be a slip of the pen. |
