Taken back to his original camp, Day was tortured for escaping, breaking his right arm again. He then was moved to several prison camps near Hanoi, where he was periodically beaten, starved, and tortured. In December 1967, Day shared a cell with Navy Lt. Cdr. and future senator and presidential candidate John McCain. Air Force Major Norris Overly nursed both back to health, and McCain later devised a makeshift splint of bamboo and rags that helped heal Day's seriously atrophied arm.
