they did look closely at McCoy...you are getting brainwashed by these guys trying to prove McCoy was Cooper..none of there evidence has ever been proven as fact! how do you write a book about this, and leave out proof other than saying "records were found"?
his photo, like many others was shown to the crew..they said no...this was a very short time after the Northwest hijacking, so memories were crisp.
show me proof "documentation" that a credit card was used, and McCoy was missing in Utah, actual proof, not words? the Seattle, and Portland FBI disagree with these guys...they never even had access to the Cooper files to begin with?
