'Shortly after midnight on the day of the invasion, Mr Pattison saw a sky "black with heavy bombers going over to soften up the beach heads." He took off at first light. "There were four lanes of shipping, 100 miles of sea, and from the air it looked as though you could skip from ship to ship from South England into Normandy." Having been shot down himself - during the Battle of Britain and while flying sweeps over France - he shot down two German aircraft that day. He had thought he would be elated at shooting down an enemy aircraft but that was not the case. "After all, the young German aviators were very much akin to what we were. They were fighting for Germany, we were fighting for Britain and France and so forth." (Source: New Zealand Herald article, 7 June 2004, page A5)
