Socorro Landing — USAF Project Blue Book Physical Evidence Report
Patrolman Lonnie Zamora observed a white egg-shaped craft land in the Socorro desert, observed two small figures near it, and watched it depart vertically. The physical evidence — four circular landing impressions, burned brush at four locations, and a rock with blue flame residue — was documented by USAF Project Blue Book investigators. Dr. J. Allen Hynek considered it his single best case. The landing impressions were formally measured and preserved. Classified CIA and USAF documents reference this case specifically.
