I first learned about Echelon with I was in the Army Security Agency. The brains for this operation was then at Ft Huachuca, Az. I think that was very early 1978. The guys in the Ops platoons who worked with the Spooks knew all about it. Not much of a secret. Funny, though, I never talked about until now. I guess I can keep a secret. But its a’’ out of the bag now
Even when I was still in canadastan, a bud of mine at the RCMP told me about it, and this right after 9/11.
USAICS August - October 1978.
I didn’t learn about it until the early or mid 1990s.
