My son LOVES this mystery. He saw this earlier today. We always enjoy discussing it. Thanks for posting!
Tell your son that the Alatraz escapees had a recent private reunion with D.B. Cooper and Amelia Earhart.
They made it by hooking their raft to a boat that brought people back and forth off the island. They had done the same thing as kids growing up.Getting off the island was the only part that anyone could not have done, and these guys just happened to have experience at that very thing.
