The Cooper Conundrum: The Skyjacker's Secret
Work the only unsolved commercial hijacking in U.S. history — the money, the tie, the jump window, the suspect file — and decide what the evidence will actually carry.

🪂 A text game you play by talking to Grok. You work the only unsolved commercial hijacking in U.S. history. The rotted twenties on the sandbar, the clip-on tie and the forty-five-year suspect file are real evidence; your investigators are invented — and nobody, this game included, knows how it ends. You get a numbered menu every turn, and you can always type something of your own instead.
On Thanksgiving Eve 1971 a man calling himself Dan Cooper took $200,000 off a Boeing 727 and stepped out the back of it into freezing rain. Nobody has ever proved what happened next.
Work the case as an FBI agent, aviation specialist, forensic analyst, reporter, or a tracker who knows the ground, chasing evidence that really exists:
- Three rotted packets of twenties on a Columbia River sandbar
- A clip-on tie carrying a hundred thousand particles
- Forty-five years of eliminated suspects
Type "fact" any time and the game breaks character to tell you what the record says, what's genuinely disputed, and what was invented for the story. Concluding that the evidence names nobody is a legitimate way to win.
Every scene quietly composes a full media set you can picture or save, and saved scenes become AI-generated reenactment films at momatio.
