Bill - This be the C-123 beastie, of which you speak? Taken at Tan Son Nhut in Sept. 1970. I too, rode this dreadful, flying crate, from Tan Son Nhut to Nui Dat.
I believe they were fitted with J85-GE-17 turbojets, which apparently was designed to improve their STOL characteristics.
I wonder what happened to WM561? I guess, more than likely, it ended up as scrap in a North Vietnamese furnace.
