On the night before Thanksgiving, a man in his forties wearing a sharp black suit and carrying a Samsonite briefcase boarded Northwest Orient Airlines Flight 305 under the alias ‘Dan Cooper.’ After takeoff, he calmly handed flight attendant Florence Schaffner a note claiming he had a bomb in his briefcase. Opening the case just enough to reveal red sticks of dynamite and complex wiring, Cooper displayed a chilling composure that unnerved the crew.

Cooper’s demands were specific and calculated:

• $200,000 in cash in twenty-dollar un-serialized denominations.
• Four civilian parachutes, ensuring that no one could trick him with a faulty single chute.

The FBI and airline management quickly complied with his instructions, realizing they were dealing with someone who possessed specialized knowledge of aviation and survival tactics.

The aircraft landed at Seattle-Tacoma Airport, where the ransom and parachutes were exchanged for the release of the 36 passengers and most of the crew. Refusing military parachutes, Cooper demanded specific civilian types and ordered the pilot to take off again under strict specifications: flying at a low altitude of 10,000 feet, maintaining minimal airspeed, and keeping the landing gear deployed.

The choice of a Boeing 727 was deliberate, as the aircraft featured a rear airstair that could be opened mid-flight. At approximately 8:00 PM, flying through a severe thunderstorm over the Pacific Northwest wilderness, Cooper vanished out the back of the plane with the ransom money. Despite extensive manhunts and decades of investigation, the ultimate fate of D.B. Cooper remains an enduring enigma.
