"So, in the event that (Harvey) was ever caught doing this (traveling under an assumed name) and was questioned about it, he could cite his FAA travel credential."--MTG
1. It was not a crime in 1963 to travel under an assumed name on a commercial airliner.
2. In the unlikely event Harvey was arrested while in or near a commercial airliner, he would likely show authorities his real ID, that he was CIA working undercover, and no police agency in the US would detain him for a minute longer.
3. I wondered if there is such a thing as an "FAA covert travel credential." AI says there was and is not.
Upon reading the Zubron memo, it says Harvey was requested to receive an "FAA credential number."
That's a horse of a different color!
AI: "Yes, the William King Harvey who was a prominent CIA officer and known as "Wild Bill" Harvey was indeed a licensed pilot. He was a key figure in a joint CIA/Army operation against Fidel Castro."
OK, maybe we are getting somewhere.
AI: "A Federal Aviation Agency (FAA) credential number circa the 1960s was a unique identification number assigned to individuals, likely for their airman certificates, which was used for tracking and regulatory purposes."
In other words, Harvey was being credentialed to fly airplanes. Like every other pilot in the US, he had an FAA credential number. Likely, the CA had an in-house office to handle these sort of time-consuming chores with other federal agencies.
The CIA has kept many useless memos sequestered since the 1960s.
