Vanished

Perhaps the most famous case of a missing person in American history, the story of D. B. (or Dan)
Cooper involves a criminal heist, a fantastic getaway, and enduring mythology. For those who have dreamed of a big score or the perfect crime, the disappearance of Cooper is the story to aspire to. On that day It goes like this.

On the day 

before Thanksgiving in 1971, a man naming himself Dan Cooper got onto Flight 305 on Northwest Airlines, which was going to fly from Portland to Seattle. Descriptions given at the time put him in a dark-colored suit with a black tie, witnesses suggesting that he looked like an executive or a businessman of some type.
During the flight, Cooper gestured towards his briefcase, revealing to the stewardess the bomb which he had smuggled aboard. Using the bomb, he hijacked the plane. The plane was forced to land, arriving in Seattle where the hijacker demanded $200,000 in cash, four parachutes, and enough food to supply himself and the crew. The passengers were turned free, while the flight took to the air with Cooper, the money, a flight attendant, and three pilots still aboard. The bills had been marked, meaning Cooper would be caught should he want to spend any of his illicit gains. They headed south. It was dark and there was a light rain. After forty-five minutes, he sent the stewardess to check the cockpit while he began ready the parachute. He tied the bag containing the money to his body, lowered the rear set of stairs and just above the dark forests of wintery Portland, he jumped out. When the flight landed, all that was found was two remaining parachutes, an empty seat, and a black tie. 

The investigation 

As soon as the hijacked plane left the airport, authorities scrambled planes and helicopters to track the plane. They missed Cooper’s exit from the plane, trailing the hijacked jet to Seattle. Over the next days, the military ordered a thousand men to sweep the area where Cooper was thought to have landed. One method of investigation involved flying the original plane over the ocean and throwing man-shaped objects from the plane door. Using this method, the investigators hoped to learn about the trajectory Cooper had taken on exiting the plane and to clarify their search in the forest, but it came to no avail. Even the top-secret SR-71 Blackbird spy plane was used to photograph the forest to try and find any trace of the man. They found nothing.  The investigation continued for many years. In 1980, just north of the Columbia River, three bundles of cash were discovered by Brian Ingram, a boy who was creating a pit for a fire in a location known as Tena Bar. Hidden just inches below the snow, the bundles still had their elastic bands attached. With the serial numbers matching $5,800 of Cooper’s marked notes, the FBI began to sweep the area. They analyzed river beds and dredged the water. Again, nothing was found. Even as recently as 2007, the FBI was willing to trust the case to Special Agent Larry Carr, providing he was able to keep costs and time to a minimum. Carr’s method of detection approached the hijacking as he might approach a bank robbery, interviewing and discussing the case with as many members of the public as possible. Though he was able to unearth several new pieces of information, there was still no trace of the man or the remainder of the money.

Update 

For many Americans, the case of Dan Cooper has now passed into legend. The missing man and his money are treated in a manner similar to the bank robbers of the old west, their fame enduring. Because of this, the discussion of his crime is now a hobby and a notable interest for many people.
For these individuals, the case rests on a few salient questions. The first is whether Cooper died when jumping from the plane. Because nobody was ever discovered and no person ever surfaced with the money, it has been hard to pronounce the suspect dead. When considering the jump, skydivers of varying experience levels have claimed that he faced a difficult prospect. For the first-time jumper, a sure death awaited. For the experienced skydiver, however, safety could be reached. Once out of the plane and landed, the cold weather could have affected his survival chances, but again, nobody was discovered. For those debating the question of Cooper’s experience levels, the request for both front and back parachutes points to an amateur jumper, while the fact that he refused attempts to instruct him how to jump indicates that he was assured enough in his own abilities. That he chose to use the parachute which he could not steer suggests a lowered chance of survival and a lack of experience, but the stewardess’s description of him assuredly putting on the parachute seems to point to a well-practiced man.  For some, the finding of the money by Brian Ingram adds complexion to the story. Twenty miles away from the money’s resting spot is the town of Ariel, the very place an analysis of the drop zone suggested Cooper would end up. For some, this suggests that the money had washed along a smaller series of rivers to rest at Tena Bar. Another theory posits that Cooper actually landed at Tena Bar and needed to bury his money to avert the chase of the FBI. Even more outlandish is the prospect of a person burying a small number of marked bills to throw the authorities off the correct scent.
