Unidentified Aerial Phenomena: Morphologies, Five Core Observables, and Hynek–Vallée Classifications
To the point
Unidentified anomalous phenomena span many shapes and extraordinary flight behaviors, are analyzed with Hynek’s proximity-based and Vallée’s morphology-based classifications to separate genuine mysteries from misidentifications, and continue to fuel debate through cases like Kenneth Arnold’s disc, the O’Hare sighting, and the Nimitz Tic-Tac encounter, with ongoing oversight by AARO and ODNI.
