From the September-October 2011 issue of The Officer, by CAPT Marshall Hansen, USNR Ret.:
Despite statistics AO continued to affect Air Force personnel, even some exposed after the War. From 1972-1982, contaminated C-123 aircraft, which dispersed the AO during the war, were flown by reserve aircrews who were continually exposed to toxins for more than a decade after the Vietnam War. Most crew members are showing ailments that can be related to AO exposure. Some have died.
