Wasn't sure which thread to post this one under but settled for here.
Recently read the suggestion that Richard McCoy was perhaps the on-the-ground accomplice of D.B. Cooper, and it's probably an idea that shouldn't be completely discounted. Particularly when you factor in McCoy's credit card was used in Las Vegas on November 24th 1971, and the collect call that was made to his home from a pay phone from near McCarran Airport later that same day.
Perhaps after having worked with Cooper 5 months earlier, McCoy thought he'd give it a go himself, and as we've seen he used almost the exact same modus operandi. In fact, probably a more refined version, because he ensured he had far more appropriate gear for the jump.
Do we know how much McCoy could have possibly known of the specifics of DBC's hijack in the 5 short months before his own?
