The FBI secretly knows who Cooper was.
The 2016 suspension said the opposite: no identification that justified a case. Released files are thick with names and thin on proof.
Unsolved is not a licence to invent a gentleman jumper or a method.
Aftermath is a closed active file and an open popular argument.
Still open
- Identity — No name has met a criminal standard. Listing favourite suspects is not a result.
- Whether the jumper lived — Himmelsbach thought not. The absence of a body is not proof of survival.
- How the bills reached Tena Bar — River, burial or placement remain argued. The serial match is solid; the path is not.
- Where the rest of the money went — About $194,200 was never authenticated in circulation or in a cache.
- Whether new DNA can matter — Without a clean identification sample from a known person, tests on old exhibits are likely to produce press, not a charge.
Myth vs record
Richard McCoy was D.B. Cooper.
McCoy committed a later, separate hijacking. The FBI compared the files and did not charge him as the Flight 305 jumper.
Cooper’s real given name was D.B.
The ticket said Dan Cooper. D.B. is a wire-service error attached to a local man who was not the hijacker.
The ransom has all been found.
Only about $5,800 was authenticated, in 1980 on Tena Bar. The rest remains missing.
Local notes
Pacific Northwest English
Oregon and Washington papers still own the first-day voice: a Thanksgiving hijacking and a man who stepped into rain. Ariel and Tena Bar are local place-names in that dialect.
Network true-crime English
United States and later British and Australian television recycled the composite and the river bills. Those hours are sources about memory, not about identity.
Classroom and legal English
When the case is taught, the usable English is NORJAK, the Cooper vane and the 2016 closure — not amateur suspect podcasts.
D.B. Cooper remains an unsolved hijacking whose English afterlife is larger than its authenticated exhibits.
