Ill-treatment denied

Another downed US flyer, Lieutenant Kenneth Enoch, wrote in his eight-page confession in April 1952 that "he (a superior) told us that our two onboard wing bombs were germ bombs and were to be dropped at Hwanjin (in DPRK) at a maximum altitude of 500 feet and at a maximum airspeed of 200 miles per hour".

In 1955, back in the US and being filmed by military cameras, Enoch called his previous confessions "absolutely false", saying "they (the Chinese) threatened me and threatened me again that I should never leave alive if I didn't cooperate".

In 2010, Enoch was interviewed by Al Jazeera English－the same team that uncovered the September 1951 document－at his home in Texas. The 85-year-old denied any ill treatment or indoctrination by his captors.

"The difficulty with this story is that many of the dates and places detailed in Kenneth Enoch's (1952) confession has since been confirmed as accurate," said the narrator of the program.

Perhaps the most powerful indictment has to come from the victims and their relatives, as well as those who insisted on talking to them, then and later.

"I went to North Korea (DPRK) and met people who had suffered the effects of germ warfare. They told me their stories, shedding tears and grimacing with anger," Mori said during his interview with The Telegraph. "They told me what actually happened and I cannot question that."
