Imagine this.

It’s a stormy Thanksgiving Eve in 1971.

A sharply dressed man in his mid40s boards Northwest Orient Flight 305 in Portland, Oregon.

Carrying a briefcase and a paper bag.

He sips a Borbin, lights a cigarette, and pᴀsses a note to the flight attendant.

Miss, I have a bomb in my briefcase.

The plane is airborne, hearts pounding as he demands 200 xosand, four parachutes, and a refuel to Mexico City or everyone dies.

Then, mid-flight over the rugged Pacific Northwest, he lowers the rear stairs, steps into the freezing night, and vanishes into the void with the ransom.

Who was he? Did he survive? 55 years later in 2026, we’re still chasing shadows.

This is the legend of DB Cooper, the only unsolved airline hijacking in history.

And tonight, we’re diving deep into the mystery that refuses to die.

So, let’s start Unsolved Mysteries with the ultimate cold case, DB Cooper.

Let’s set the scene properly because this story begins not with a bang, but with a quiet purchase at the Portland International Airport ticket counter.

On November 24th, 1971, a man who identified himself as Dan Cooper, later misreported by the media as DB, Cooper, due to a journalistic error, paid 18.

52 in cash for a one-way ticket to Seattle on Northwest Orient Flight 305.

He was described as a nondescript businessman, mid-40s, about 5’10” to six tall, 170 or 180 lbs, olive or sworthy complexion, brown eyes, dark hair, wearing a black suit, white shirt, narrow black tie with a mother of pearl tie pin, loafers, and carrying a black attache case and a brown paper bag.

He boarded the Boeing 727 without incident.

Took seat wait in the rear, ordered a Borbin and water, and smoked cigarettes.

The flight took off at around twinsen 50 p.

m.

with 35 pᴀssengers and six crew members aboard, including pilots Captain William Scott and first officer William Rettoac and flight attendants Florence Shaner and Tina Mucklo.

Little did they know this routine 30 minute hop would become the stuff of legends.

About 20 minutes into the flight, as the plane cruised at 10,000 ft, Cooper leaned over and handed a note to Florence Shaner, the 23year old flight attendant seated nearby.

Thinking it was just a phone number from a lonely pᴀssenger, she pocketed it without reading.

But Cooper whispered urgently.

Miss, you’d better look at that note.

I have a bomb in my briefcase.

Shaner unfolded it.

I have a bomb in my briefcase.

I will use it if necessary.

I want you to sit next to me.

You are being hijacked, she complied.

And Cooper opened his briefcase just enough to reveal red cylinders.

Dynamite sticks, he claimed.

connected by wires to a battery.

He dictated his demands to 200 dousand in unmarked negotiable American currency, all in 20s, four parachutes, two main and two reserves.

And upon landing in Seattle, the plane refueled for a flight to Mexico City.

with the flight path keeping the plane under 10 thousand ft, flaps at 15°, landing gear down, and no faster than 200 knots.

He specified the air stairs, the rear ramp of the 727 must remain down during takeoff.

Shaner relayed this to the cockpit and the pilots alerted air traffic control.

The airline president, Donald Narup, authorized the ransom payment, prioritizing safety.

The plane circled Puget Sound for two hours while authorities scrambled.

FBI agents in Seattle ᴀssembled the money.

$10,020 bills pH๏τographed and serial numbers recorded totaling 200inon and sourced the parachutes from a local skydiving school.

Cooper, calm and polite, chatted with the crew, even offering them cigarettes.

Here is the payment.

He knew the terrain, pointing out Tacoma below without being told, and demonstrated aviation knowledge, mentioning the 727’s ability to fly with stairs down from military tests.

He insisted no funny business with the parachutes, suspecting sabotage.

At 5 and 39 p.

m.

, the plane landed at Seattle Tacoma International Airport.

Cooper released the pᴀssengers who disembarked unaware of the hijacking until later, but kept the crew, the pilots, flight engineer, and Tina Mucklo.

The ransom and parachutes were delivered via a fuel truck.

Cooper inspected them meticulously.

He cut cords from one reserve chute to tie the money bag to himself and allowed refueling.

He specified the route south toward Mexico City via Victor 23 Airway with a stop in Reno if needed for fuel.

At 7 to 40 p.

m.

the plane took off again now with just Cooper and the four crew members.

He directed them to the cockpit, closed the curtain, and warned against interference.

Somewhere between Seattle and Reno around 1,800 to 8C13 p.

m.

over the dense forests of southwestern Washington near Lake Merwin or Arieriel, a pressure bump indicated the air stairs had deployed fully.

Cooper had dawned a parachute, tied the money to his waist, and jumped into the 200 MIP slipstream, temperature around 7° Fahrenheit, dressed only in his suit and loafers.

The plane landed safely in Reno at 10:15 p.

m.

, but Cooper was gone.

No trace, no body, no parachute, no money, despite immediate searches by military helicopters and ground teams.

The FBI launched operation no RJK, one of the largest manhunts in history, interviewing hundreds, scarring 28 mi of riverbank and deploying submarines in Lake Merwin.

Nothing.

For years, the case tantalized investigators.

In 1980, a breakthrough or a tease 8year-old Brian Ingram vacationing on Tina Bar along the Columbia River near Vancouver, Washington found three bundles of 20s totaling 5 Thunders 800 serial numbers matching the ransom.

Weathered but intact, it suggested the money had been buried or washed up, perhaps from Cooper’s failed landing.

But how did it get there? Dredging theories emerged, but no more money surfaced.

The rest of the 194th 200 vanished like Cooper.

The FBI recovered fingerprints.

None matched known criminals and a clip on Tai left behind which in later years yielded over 100 Zaros and microscopic particles.

Rare alloys like тιтanium smeared with bismouth strontium sulfide and even commercial salt crystals.

These pointed to aerospace or chemical industries, perhaps Boeing or a subcontractor, suggesting Cooper was an engineer or technician with specialized knowledge.

Suspects piled up like autumn leaves over one investigated by the FBI with dozens publicly debated.

Let’s start with Richard Floyd McCoy Jr.

, a Mormon Sunday school teacher, Army veteran, and helicopter pilot.

Just 5 months after Cooper in April 1972, McCoy hijacked a United Airlines flight from Denver demanding 500,000 and parachutes, then jumped over Utah.

He was caught days later with the money, sentenced to 45 years, but escaped prison using a fake gun made from dental paste only to die in a shootout.

Similarities abounded.

handwritten notes aviation no how even the same no funny stuff phrase his kids later claimed he was Cooper but physical descriptions didn’t match McCoy was younger had different features and Alibus placed him elsewhere ruled out but he remains a fan favorite then there’s Sheridan Peterson a former marine smoke jumper and skydiving instructor who worked in Nepal and resembled the sketch he was 44 at the time, smoked and had parachuting expertise.

Investigator Eric Ulus was 98% convinced in 2018, citing Peterson’s risk-taking personality and a comic book alias, Dan Cooper, from his library, but Peterson denied it before dying in 2021 at 94, and no hard evidence linked him.

Ulis later withdrew the claim.

Robert Rackstraw, a Vietnam vet with piloting skills, explosives training, and a criminal record, became a prime suspect in documentaries.

He allegedly taunted authorities with coded letters, and his uncle was a paratrooper trainer.

Rackstraw, who died in 2019, dodged questions, but was cleared by the FBI due to age mismatch.

He was 28 in 1971, too young for the mid-40s description.

LD Cooper proposed by his niece Mara Cooper in 2011 was a logger who vanished around the hijacking.

She claimed overheard family talks about a plane hijacking and recognized the sketch.

A fingerprint on a guitar strap didn’t match and the lead fizzled.

More recently, Vince Peterson, a Pittsburgh тιтanium research engineer, emerged from particle analysis on the TAI.

Ulis in 2023 2024 linked a patent for a тιтanium alloy to Crucible Steel, where Peterson worked, a Boeing subcontractor.

Peterson, who died in 2002, matched the age, smoked, wore ties, and had Northwest ties.

Ulis called him compelling, but no DNA confirmation yet.

From the 2025 2026 FBI file releases, parts 108 to 113 totaling thousands of pages, new names surfaced, chilling in their obscurity.

A wheelchair bound man was briefly considered but dismissed outright.

A man confined to a wheelchair did not hijack the plane.

Donald Sylvester Murphy, a hoaxer, claimed to be Cooper in 1972 to extort 3000 from Newsweek using forged bills.

He was convicted of fraud.

William Franklin Crane, a former paratrooper from Reton, Washington, was reported by his girlfriend for suspicious behavior, arriving late post, hijacking with mud on his shoes, selling a plane, and acting nervous.

Hoodlams allegedly sought him thinking he had the money cleared but intriguing.

Raymond Sydney Russell, a 48year-old with Air Force background, Boeing inspector experience, cargo piloting, and Seattle air traffic control stints, was tipped in 1976.

He matched the sketch per an informant, disappeared around the hijacking time, and had an adventurous demeanor.

But Alabus placed him on the east coast.

A facial scar didn’t match and he was too short.

The FBI cleared him, but enthusiasts on Reddit and Facebook hailed him as fantastic.

Though experts like Ulus dismissed him, focusing instead on Thai particles, suggesting Albany Research Center employees.

Other theories swirl like the storm that night.

Did Cooper survive? The unsteerable military reserve chute, non-jumper attire, and rugged terrain suggest death.

Supported by the 1980 money find, possibly dispersed by river currents after a fatal landing.

Yet no body.

Some speculate he was a CIA operative.

The hijacking a test or cover up given his aircraft knowledge from Vietnam error ops or a hoax.

unlikely with real money paid.

Alien abduction fun, but no.

Recent 2026 files revealed Cooper’s caution.

He demanded back all notes in a matchbook to erase prints, inspected parachutes.

East1 was a dummy sewn shut.

Did he know conflicting witness accounts Latin appearance via white male muddied the sketch? In 2024, a North Carolina parachute find sparked buzz, but it didn’t match.

Cooper days with lookalike contests.

He’s inspired copycats, тιԍнтened airport security, ending unscreened boarding.

Why unsolved? Cooper’s professionalism, no violence, polite demeanor, left scant traces, no DNA match yet, though the tie holds partial profiles.

In 2016, the FBI sheld active pursuit, but releases continue fueling amateurs.

Was he McCoy, Rackstaw, Peterson, or someone lost to time? Did he die cold and alone or live richly anonymous? As we wrap this deep dive, remember mysteries like this remind us truth fears no investigation.
