A flight attendant on D.B. Cooper's planehas spoken out about the events leading up to his disappearance.

On 24 November, 1971, a mysterious man who gave the name Dan Cooper boarded the Boeing 727-51 flight from Portland, Oregon to Seattle, Washington.

Shortly after taking off, he revealed to a stewardess that he had a bomb on him, demanded $200,000 (roughly $1.4 million - £1.1 million - today) and four parachutes, before escaping.
