2013 Aguadilla, Puerto Rico — Analysis of an Unidentified Anomalous Phenomenon
TL;DR — A 162-page technical analysis of DHS thermal video from Aguadilla — the most rigorously worked UAP case document in circulation.
162 pages analysing a single Homeland Security thermal video taken from an aircraft tracking an unidentified object near Aguadilla, Puerto Rico in 2013.
What distinguishes it from the genre is method: the report works through the infrared imagery frame by frame, reconstructing trajectory, apparent size and velocity from the sensor’s own parameters, and explicitly tests mundane explanations before rejecting them.
⚠️ Read it as an exercise in inference from thin instrument data, which is what it actually is. Whether the conclusion holds is contested; the working is unusually exposed, which is the reason to keep it.
