How many pilots killed in Vietnam?

During WW2 & and possibly Korea, the US Military utilized some ENLISTED MEN as pilots. By Vietnam, all US Military pilots were officers. Therefore: approximately 6,600 US Military officers were killed in the war. The USAF lost about 2,584 men and the USN lost about 2,555 men. The USAF and USN together lost well over 2,000 fixed wing aircraft. The US Army lost well over 8,000 rotor-wing aircraft. Approximately 2,000 US UH-1 Iroquois (Huey) helicopter crewmen died in the war. Figuring 10,000 plus shot down aircraft/6600 dead officers/subtracting the ground officers (US Army/US Marine Corps/US Navy Riverine Forces/etc)...an educated calculation of US military pilots killed in the Vietnam War would be between 2,000 and 3,000 Airmen.
