A 29-year Air Force veteran, Johnson served in both the Korean and Vietnam Wars. Johnson spent nearly seven years as a Prisoner of War, more than half of that time in solitary confinement.
Coincidentally, this week in 1973 as one of the longest held captives, Johnson finally left Hanoi on February 12, 1973 and returned home to Texas on February 17, 1973.
