D.B. Cooper: The Only Unsolved US Aircraft Hijacking (1971)

On November 24, 1971, a strange and terrifying event unfolded in the skies over the Pacific Northwest. Delta Air Lines Flight 305, bound for Seattle-Tacoma International Airport from Portland, Oregon, disappeared into an enigma that remains unsolved to this day. This is the story of D.B. Cooper—the man who hijacked a Boeing 727-100 and vanished without a trace.

The History and Background

D.B. Cooper—or rather, D.B. Cooper, as he signed his ransom note—was a mysterious figure whose identity remains unknown. In 1971, the United States was in the midst of the Vietnam War, and public sentiment was divided on the conflict. Yet, it is the peculiar nature of this crime that sets it apart: the audacious act, the precise execution, and the complete disappearance without a trace.

Key Events or Sightings (With Specific Dates/Names Where Real)

The events of November 24, 1971, were meticulously recorded. At approximately 3:08 PM Pacific Standard Time, D.B. Cooper boarded Delta Air Lines Flight 305 in Portland, Oregon, with a suitcase and a loaded .38 caliber pistol. He had purchased a one-way ticket to Seattle.

3:24 PM: Cooper approached the flight attendants, stating he had a bomb on board and demanded that all passengers be seated and remain quiet. He then informed the crew about his plan to hijack the aircraft. By 5:00 PM, the plane landed in Seattle, where Cooper received $200,000 in ransom.

7:15 PM: The plane took off from Sea-Tac Airport with Cooper on board. He instructed the flight attendants to hand over more money, eventually receiving a total of $96,000. Around 8:34 PM, he made his final request—two parachute suits and a map.

11:25 PM: At this point, Flight 305 was flying at an altitude of 10,000 feet over the Columbia River Gorge in Washington State. Cooper instructed the crew to depressurize the cabin so he could get out safely. He then jumped from the aircraft with a suitcase and his parachute.

12:07 AM: The plane landed at Seattle-Tacoma Airport without him. No sign of D.B. Cooper or his parachute was ever found, nor did anyone report seeing him after that night.

Witness Accounts or Evidence

#### Flight Attendants’ Testimony

Flight attendant Dorothy Seifert recounted the events in detail during her testimony:

3:08 PM: “Mr. Cooper came to me and said he had a bomb. I believed him because his demeanor was very serious.”
5:00 PM: “He asked for $20,000. We gave it to him, but not until the plane landed in Seattle.”

#### The Parachute

The parachute that Cooper used was recovered by authorities and remains a key piece of evidence. It is marked with the initials “D.B.C.” and a serial number, providing some clues about his identity.

Investigations or Research

Over the years, numerous investigations have been conducted to solve the case. FBI agents, private investigators, and even conspiracy theorists have all delved into the mystery. Despite exhaustive searches, no definitive evidence has emerged linking D.B. Cooper to any known individual.
