Donald James Matthew Blakeslee (September 11, 1918 – September 3, 2008) was an officer in the United States Air Force, whose career began as a pilot in the Royal Canadian Air Force and flew Spitfire fighter aircraft, during World War II. He then became a member of the Royal Air Force Eagle squadrons. He arguably flew more combat missions against the Luftwaffe than any other American fighter pilot.
By the summer of 1942 he was a flight leader, and received the Distinguished Flying Cross. He then completed his first tour of duty, clocking 200 combat hours with 3 victories.
Blakeslee had studiously avoided being part of the American volunteer Eagle Squadrons, claiming "they played sister in making their claims." But when told he would be assigned to be an instructor pilot, he finally volunteered to be sent to No. 133 "Eagle" Squadron as its Commanding Officer, which was the only way he could remain on combat status. During the raid against Dieppe, France on 18 August 1942, Blakeslee shot down an FW-190, and another on the 19th, thus achieving "ace" status.
The 8th Air Force Command eventually agreed to the request, provided the pilots were operational on the P-51 within 24 hours of receiving them. Blakeslee agreed, instructing his pilots to "learn how to fly them on the way to the target".
In March 1944 Blakeslee was in the first Mustang over Berlin. Escorting the massed daylight raids of the 8th Air Force over Occupied Europe while under Blakeslee's command, the 4th FG became one of the highest scoring groups of VIII Fighter Command. The 4th's aggressive style was very effective, and the 4th Fighter Group passed the 500 kill mark at the end of April, 1944.
The next landmark for Blakeslee was leading the first "shuttle" mission to Russia on 21 June 1944, flying 1,470 miles in a mission lasting over 7 hours.
Don Blakeslee was finally grounded in September 1944, after the loss of several high scoring USAAF aces. He had accounted for 15.5 kills in the air and 2 more on the ground and had flown over 400 operational sorties.
Blakeslee retired from the United States Air Force in 1972 with the rank of Colonel.
