The President of the United States of America takes pleasure in presenting the Distinguished Flying Cross to Rear Admiral (Retired) Luis DeFlorez, United States Navy, for extraordinary achievement while participating in numerous aircraft flights throughout his naval career. Responsible for the original conception, design and flight-testing of aircraft instrumentation which included the first bubble sextant and the first complete audio flight reference, Rear Admiral DeFlorez made many major contributions to the development of cockpit instrumentation and controls, air speed indicators and night lighting. In the forefront of naval aviation as inventor, designer and pilot, he was recognized for his imagination and inventive skill in this field by the Scientific American Prize for Aircraft Improvement in 1934, and the Collier Trophy in 1943.
