After the Battle of Midway, the USAAF began redeploying fighter groups to Britain as part of Operation Bolero and Lightnings of the 1st Fighter Group were flown across the Atlantic via Iceland. On 14 August 1942, Second Lieutenant Elza Shahan of the 27th Fighter Squadron, and Second Lieutenant Joseph Shaffer of the 33rd Squadron operating out of Iceland shot down a Focke-Wulf Fw 200 "Condor" over the Atlantic. Shahan in his P-38F downed the "Condor"; Shaffer, flying either a P-40C or a P-39, had already set an engine on fire. This was the first Luftwaffe aircraft destroyed by the USAAF.
