W. L. "Lou" Everett (November 28, 1924 – April 27, 1965), was a United States Air Force fighter pilot and test pilot.
Lou Everett was born on November 28, 1924, in Brooklyn, New York. He graduated from high school at seventeen during World War II, and wanted to fly fighter aircraft for the United States Navy. Because he was too young for the Navy Cadet program, he enlisted in the Army. Within a few months, he transferred to the United States Army Air Corps and began training as a fighter pilot assigned to fly the P-51 Mustang. Stationed in Florida, he was awaiting assignment to go overseas when the war ended.
Everett joined the Mississippi Air National Guard, attended Millsaps College, and continued to fly by crop dusting and instructing at a local air school. While attending Millsaps, he married Betty June Coleman and soon after the couple moved to Starkville, Mississippi, where Lou enrolled in the Aero Physics Department at Mississippi State University. In December 1950, the Mississippi Air National Guard was called to active duty because of the Korean War. Shortly thereafter, Everett was called to serve in Korea, where he flew AT-6 Texans on forward air control missions.
Everett returned to the United States to resume his education at Mississippi State. He graduated in 1954 with a degree in Aeronautical Engineering and joined Chance-Vought in California as an engineer. In 1955, he was hired by Ryan Aeronautical Company as their second test pilot for the X-13 Vertijet, joining Ryan’s Chief Test Pilot, Pete Girard. The X-13 was the world’s first pure jet VTOL aircraft, and Girard and Everett were the only pilots to fly it. As a result of their research work on the X-13, the two men received awards from the New York Academy of Sciences. During this time, Everett became one of the original 17 members of the Society of Experimental Test Pilots.
