Long lines formed when five DC-3 aircraft were on display at Reykjavík Airport last night. Guests were invited to view two of them from the inside. The planes, part of a mission called D-Day Squadron, are some of the 15 DC-3 aircraft flying from Oxford, Connecticut, to Normandy, France, where they will take part in a ceremony June 6th, commemorating the Allied invasion of Normandy 75 years ago.
