Lt. Jennifer Knapp, an aerospace experimental psychologist and former naval flight officer, stands for body measurements by an anthropometry scientist of the Naval Air Warfare Center Aircraft Division at Naval Air Station Patuxent River, Maryland. Knapp is the military liaison helping lead the Navy's first comprehensive study since 1964 to update aviator size requirements, improve aircrew gear and equipment, and expand access for prospective future aviators. The command seeks participation by more than 4,000 active-duty enlisted and commissioned aviators, flight officers, and aircrew members across the country on its tour of the Navy's most populous air bases between May 9 and December 2023.
