In a report by West Virginia Public Broadcasting, Air Force reservists were quoted as saying that residue of Agent Orange caused damages to their health. Agent Orange is a defoliant chemical that the U.S. used in the Vietnam War. It was sprayed using C-123 planes, which were then used for a decade after the war for other purposes.
The residue of the chemical remained on the planes—something which the Air Force reservists didn’t mind at the time, noting only that the planes smelled bad. After retiring, they developed some health issues such as diabetes, non-Hodgkin lymphoma, and prostate cancer, which the U.S. Department of Veterans Affairs (VA) acknowledge have been associated with Agent Orange.
