On January 27, 1973, the Paris Peace Accords, which ended the Vietnam War, was signed.
However, on February 5, 1973, the Baron 52, an electronic warfare C-47 aircraft, began a covert and illegal mission to locate North Vietnamese tanks traveling southbound and monitor movement on the Ho Chi Minh trail.
Aboard were two teams: the flight crew and a group of technology specialists.
En route, the aircraft was hit by anti-missile fire. After notifying the control tower, the plane went missing, and half of the crew was never found.
Even 4 decades later, many, including some of the men's family members, still believe that the remaining four airmen were captured by the North Vietnamese and possibly even sent to the USSR to be tortured.
Is the mystery of the Baron 52 an unfortunate accident?
Or did the U.S government bury what could be the last case of prisoners of war taken by Vietnam?
