Dave Dean was my Father’s US salesman with his own company Dean Printing Systems in Chicago. He told me about his Vietnam War service when I first met him in 1988, saying his military career had been quite short after he "broke nearly every bone in my body” in a parachute training accident when he landed in the jungle canopy in Vietnam. He said he recovered in the Philippines before opening a go-go bar there, besides the huge US Clark air base - a hub of the CIA’s Air America and a place where they trained Hmong gurrilla fighters.
Dean’s mentioned by name in Samuel Zaffiri’s book about the battle for Hamburg Hill in 1968 and the only in-country parachute training after that was in 1971/72, run by the top secret MACV-SOG special forces unit.
In late November 2019 I read about the MACV-SOG parachute training and connected to Dean’s story about his parachute training accident. I also saw that training was run by special forces veteran Billy Waugh. Waugh was medically discharged from the army circa 1972 - the same time as Dean told me he was - and then became a special forces contractor. In his 2004 autobiography Waugh admits trying Al Qaeda fighters in 1990s Yemen, providing an even stronger link to my metings in Yemen.
I had found evidence that Dave Dean’s military service, my Father’s machine sale to Yemen and Billy Waugh’s CIA activities in 1990s Yemen were connected were very likely connected. I reported this to the security services and published it as a report in January 2020.
