The President of the United States of America takes pleasure in presenting a Gold Star in lieu of a Second Award of the Distinguished Flying Cross to Lieutenant Commander Roger Carlquist, United States Navy, for extraordinary achievement in aerial flight as a Project Pilot on the F3H aircraft at the Naval Air Test Center, Patuxent River, from October 1958 to March 1959. Assigned the task of evaluating the F3H aircraft under extremely hazardous and adverse weather and flight conditions, Lieutenant Commander Carlquist was instrumental in obtaining invaluable information as a result of these flights. On one occasion when engine seizure was imminent and the fire warning system indicated fire, he chose to remain with his aircraft, and carried out a successful landing. During another flight, when all the pressure flight instruments failed and the aircraft was badly damaged by hail and ice, he again made a successful landing, thereby permitting a detailed engineering analysis of the damaged engine.
