How can i link science with D-Day?

Question

Does anyone know how i can find a science related item from D-Day (June 6th, 1944)?

Answer 1

Weather was a major factor in the decision of exactly when the operation was launched.  Gen. Eisenhower delayed the onset of D-Day by a couple of days as the result of heavy seas and overcast, rainy conditions.  Delaying it any longer would have risked detection by the Germans thus the loss of the vital element of surprise.

Gen. Eisenhower's meteorologist therefore played a key role in the success of the affair to say nothing of the eventual outcome of the entire war.
