Coincidentally, while we are covering this case - there was a break after years of evidence going cold. Just this week children of a man they claim to be D.B. Cooper finally broke their silence now that their mother has passed and have a parachute they claim their father used in the infamous sky jacking - we also speak with former flight attendant Derrick Danzl for an exclusive take on what it's like to be part of a flight crew.

D. B. Cooper has never been identified even though he hijacked a Boeing 727 aircraft in United States airspace on November 24, 1971. During a flight from Portland, Oregon, to Seattle, Washington, Cooper told a flight attendant he had a bomb, demanded $200,000 cash and four parachutes upon landing in Seattle.

Somewhere south of Seattle D.B. opened the escape hatch and parachuted into the black of night. Cooper's whereabouts have never been found.
