#18: D.B. Cooper and His Audacious Plane Hijacking

In 1971, Dan Cooper, masquerading as an ordinary businessman, hijacked a Portland to Seattle flight. His calm demand for $200,000 and parachutes, threatening to blow the plane up, stunned the crew. His ordinary demeanor hid an extraordinary plan.

After securing his demands and releasing the passengers, Cooper ordered the plane to fly to Mexico City. In a daring act, he jumped mid-flight with the cash, disappearing forever. Despite extensive searches, his fate remains a mystery, with many doubting his survival.
