Premise: The 464th Troop Carrier Group was a theater airlift unit of the United States Air Force during the Cold War. It served in the United States under Tactical Air Command between 1953 and 1957. The group operated Fairchild C-119 Flying Boxcar and Fairchild C-123 Provider aircraft as the flying element of the 464th Troop Carrier Wing until being inactivated when the wing was reorganized.
Hypothesis: The United States Air Force currently has 465 troop carrier groups.
