AFOSI LaPaz Catalog raw data

NICAP · 22 pages · text from the file's own layer

This document is a NICAP-hosted table of AFOSI raw data summarizing 209 sightings of unknown aerial phenomena, listed from January 1943 through May 1950. Most reports come from New Mexico sites such as Los Alamos, Sandia Base, Albuquerque, Alamogordo and Vaughn, with others from Camp Hood, Texas, and Arizona. For each sighting it records the observers, the reliability rating, direction, color, duration, shape, speed and how the object disappeared. It sorts the cases as green fireball phenomena, disks or variations, or probable meteors.
