THE FILING CABINET

200 files. Each covers one conspiracy, mystery, or anomalous event, and each is graded on the evidence, nothing more, nothing less. Some turn out to be real. Most don't. The interesting ones are still open.

New here? Start with six routes in. Or filter below, or sort the whole cabinet by date, by what the evidence rests on, or by how it gets graded. If you would rather not choose, start at a door and go down.

PROJECT MKULTRA

CIA mind-control research program

D.B. COOPER

The only unsolved commercial skyjacking in U.S. history

THE GULF OF TONKIN INCIDENT

The attack that launched a war didn't happen

August 2 was a real firefight; August 4 was weather, jumpy sonar, and skewed intelligence. The NSA's own declassified history says so, after the resolution had already bought a decade of war.

AREA 51

The secret base was real. The aliens were airplanes.

THE TUNGUSKA EVENT
