Second World War
McPherson is notable for being the pilot of Bristol Blenheim bomber N6125 of No. 139 Squadron RAF, which was the first British aircraft to cross the German coast after Britain had declared war on Germany. His mission on 3 September 1939 was to look for potential targets in North Germany and the German fleet on the Schillig Roads near the port of Wilhelmshaven from an altitude of 24,000 feet. He took off from RAF Wyton in cold, cloudy weather and experienced severe icing on the aircraft. Amongst the ships he and his crew observed were the German cruisers Admiral Scheer and Emden.
Their sightings were reported upon their return to base as the aircraft wireless transmissions failed. An air raid was then ordered on the ships by fifteen Blenheims from No. 107 Squadron, No. 110 Squadron, and No. 139 Squadron. The weather conditions were very poor when they set off on their bombing mission the next morning. Several bombs did not detonate and four aircraft from No. 107 Squadron were shot down, with two survivors becoming the first Bomber Command airmen to be taken prisoner in the Second World War. An aircraft from No. 110 Squadron was also shot down and crashed into the bow of the cruiser Emden (curiously the pilot killed in the crash was also named Emden). For his role in the action, Flying Officer McPherson was presented with one of the first two Distinguished Flying Crosses of the war by King George VI.[2][3]
