January 17, 1953 — Guatemala City, Guatemala — Blimp-Like Object Sighted by Geologist

3:55 p.m. Geologist/salesman John Townsend Sackett is riding in a bus with about a dozen passengers near Guatemala City, Guatemala, when he observes a brilliant greenish-gold object, shaped like the Goodyear blimp. It is later described as being about twice the size of a DC-3. The object is traveling at about 400 mph straight and level in a northwesterly direction at about 6,500 feet. It almost stops in mid-flight then rises vertically about 1,500 feet, hovers for about 2 seconds, then immediately resumes flight at a new altitude. The object is lost to view because of intervening terrain. [Eberhart]
