Recommendation (dated 24 March 1943 when he had flown a total of 413 hours. Of these, 140 had been flown in previous six months. He had 40 sorties (151 hours 30 minutes operational time)):
"Flight Lieutenant MacKenzie has carried out 40 long range reconnaissances over enemy occupied territory. Thirty have been flown since he arrived in North Africa and many of these have been outstandingly successful flights over targets which include the ports of Marseilles, Toulon, Genoa, Spezia, Leghorn and Cagliari, as well as many aerodromes and defence lines in Tunisia. During a period when the unit suffered serious losses over Tunisia he never failed to show great keenness and zeal to fly on operational sorties, and by his excellent example he did much to uphold the morale of the pilots in his flight.
