February 4, 1953 — Yuma, AZ
1:50 p.m. US Weather Bureau observer Stanley H. Brown in Yuma, Arizona, tracks with a theodolite a white, oblong object. It is surrounded by a thin white mist and flies straight up and levels off. After 20 seconds, the object is joined by a second one that flies away twice and returns. Both are lost to sight behind clouds to the south-southwest. The sighting lasts 5 minutes. [Eberhart]
