Fifty-three years ago a plane disappeared in Vermont, not to be seen again. Until now. On a snowy night in January of 1971, a small corporate jet carrying five people mysteriously vanished. It never arrived at its destination, Providence, Rhode Island. Dozens of searches ensued, but the plane and its passengers and crew were never spotted. Experts now believe they���ve found the wreckage of the long-lost jet at the bottom of Lake Champlain.
