Bill Person
Vietnam | 553rd Reconnaissance Wing
Bill Person gives a behind-the-scenes look at the sensor program in Vietnam. Using technology adapted from the Navy's anti submarine program, audio and seismic sensors were placed along the Ho Chi Minh Trail and inside North Vietnam. In one case, a recording of two amorous VC led to the destruction of an ammo dump. Curiously, Person was told not to share any more targets with the FACS. (8:21)
