Kristina: Contact Steve Sherman in Houston, TX (713-683-9076).He has produced a great CD entitled "MACVSOG Documentation Study and Command Histories", copyright 2002, RADIX Press. I have used it for research on SOG and my Air Force role in flying for them. The CD has most of what is available anywhere, even though a lot of it is still classified or has been "redacted" from the files.
Feel free to contact me if you need any more help. Richard, Air Force MC-130 Straygoose pilot, Nha Trang, 1967.
