In C130s, CV2, Hueys and occasionally in C123s. Those were the Agent Orange aircraft. You would climb in the back of these aircraft and they were usually a wreck inside. No wheel covers, so you'd be enjoying a smooth takeoff and suddenly a 6' tall filthy dirty wheel would rise up still doing 150mph throwing crap all over the inside where the people were. Literally a spinning 300lb chunk of rubber within a foot of you. If they had done some agent orange, you were now sitting in it.
I have peripheral neuropathy, my legs and feet have no feeling from the shin down, I have had it for 15 years. Doctors think that it is diabetes until they check the pulse and it is wonderful in the feet and legs. It is the number one complaint of VN vets and unless you claimed it withing 6 months of discharge, tough titty. I was 23 years old at that time and so tough titty. I had no high blood pressure when I was drafted and I had it when I got out. There was a lot of really bad stuff going on over there, fevers, parasites.....I can't imagine what Jim was exposed to down in the filthy delta of the Mekong .
