D.B. cooper

According to public releases from the FBI, they have closed the investigation into the only unsolved hijacking on U.S. soil in history. But two credible experts say they know who he was, but refused to think he might have been a different person using an alias.

A former Navy SEAL nearly met the same fate as some historians believe met the mysterious D.B. Cooper when he jumped out of a Boeing 727 airliner in darkness between Portland and Seattle in 1971.
