We all have cases that for some reason or the other haunt us, that we can't stop thinking about. These are the ones that might sometimes keep us awake at night, as we turn over all the possibilities in our mind. 

For me, the story of D. B. Cooper is definitely one of those cases. It's not a murder case but it is a missing person case. On November 24, 1971, a man the world has come to know as D.B. Cooper hijacked a passenger plane and demanded a ransom of $200,000. After he got his money, he parachuted out into the night sky-- and was never seen again. 

Who was he? Why did he do it? What happened to him after he leapt out into the darkness?

To get an idea of some of the possibilities, we turned to Eric Ulis. Eric is a widely recognized expert on the case-- you may have seen him discuss it on the History Channel and CNN. And he has some ideas on how the mysteries surrounding Cooper can finally be solved.
