This is why I don't like to get hung up on suspects. they all have the same similarities, but zero proof. it hasn't even been verified Cooper worked for Boeing, let alone the SST program. it's all speculation. it's possible, but they all build around this. then they take the sketch as a photo vs a sketch..these are the problems the FBI must of went through for decades. we hear the witnesses to the actual crime speak decades later, and show obvious signs of memory loss, but not people with suspects, they speak like it was yesterday.
When Derek finds some proof, I'll take a look. until then, I'll pass...
