According my father, my grandfather (a telecoms engineer) helped lay the cabling in this complex. Somehow he became privy to some of the details of the invasion, and late on the night of June 5 or very early in the morning of June 6 1944 took my four-year-old father up a hill to watch the airborne forces covering the sky as they made their way to Normandy.
