Ciudad Valleys (Mexico) — August 18, 1953

Approximate date. Cab evening driver Salvador Villanueva, 40, observed two creatures 12 m tall wearing coveralls with wide, shiny, per- forated belts, metal collars, and small, black, shiny boxes on their backs. They had helmets under their arms. The witness thought they were pilots of Indian race. One of them spoke to him in Spanish, “stringing the words together” in a strange accent. Trivial mat- ters were discussed until dawn, when they returned to their craft, 13 m in diameter, through a staircase under the lower disk. The witness ran away when invited to follow them. The object rose with a pendulum mo- tion and shot up vertically. (Humanoids 32; FSR 56, 2)
