This is an extract from the operations record book of 439 Squadron Royal Canadian Air Force, which supported 3rd Canadian Division on Juno beach. Each air squadron kept an operations record book with details of its operations, including names of aircrew and type of aircraft used. Typhoon aircraft were normally used as fighter-bombers and posed a great threat to German vehicles moving by day.
