409 Squadron RCAF: The Nighthawks
An outstanding pilot, W/C. Petersen was one of the first to ferry a Hudson aircraft from Canada to Great Britain. Shortly after his arrival in England he was called upon to form a Nightfighter Unit to be known as 409 (RCAF) Squadron. Within a month after he had received the first aircraft, W/C Petersen had the Squadron fully operational on Defiants, a tribute to his organizing ability. Shortly after, the Squadron began to re-equip with Beaufighters. While checking out one of the latter, W/C Petersen was killed in a flying accident on the 2nd Sept. 1941.
