“…By summer 1965, more than thirty American airmen had been killed or were presumed missing in action and a dozen had been captured, including the first Air Force POW, Lieutenant Hayden Lockhart.

[8][1] The prisoners were paraded, handcuffed in pairs,[9] and marched down the main street of Hanoi while angry crowds of people screamed, spat and threw objects at them.

[1][10] A photograph,[11] (published in Look magazine in 1970) showed Lockhart supporting fellow prisoner of war, Phil Butler, who was dazed after being struck by a thrown bottle.

[12] The prisoners supported each other and communicated using a tap code that Lockhart's fellow POW, Carlyle "Smitty" Harris, had learned in a survival school.

[3] Lockhart received an Air Force Institute of Technology assignment to the University of Southern California at Los Angeles to complete his graduate degree.
