His 3rd Distinguished Flying Cross with Valor Citation reads:

Captain Ernest C. Fiebelkorn, AO753639, United States Air Force (now missing in action) distinguished himself by heroism while participating in aerial flight as pilot of an F-82 type aircraft on 6 July 1950. Captain Fiebelkorn led a flight of four F-82 all-weather fighter type aircraft to the Suwon-Seoul area, Korea, upon very short notice, and over a long distance under extremely adverse weather conditions. The mission of the flight was to contact a forward control aircraft in order to receive instructions for strafing a group of enemy tanks that had broken through our lines. The entire target area was covered by a low under cast and after several unsuccessful attempts by Captain Fiebelkorn to contact the controller aircxraft, he did voluntarily let down through the dangerous undercast over mountainous terrain, in a final attempt to make contact and engage the enemy. No more was heard from Captain Fiebelkorn by the remainder of the flight waiting aloft. The exemplary courage and selfless devotion to duty demonstrated by Captain Fiebelkorn reflect the highest credit upon himself and the United States Air Force.
