How to read official files

A declassified file shows what an agency recorded, not what was true. Most UAP files are witness reports, and "unresolved" usually means nobody collected enough data to resolve them. Look for raw sensor data, more than one independent sensor, and chain of custody: that's what would turn a sighting into evidence.
