Retired U.S. Army Colonel Horace S. Eakins and Sylvester Bentham were 4 miles east of San Pablo, and 4.1 miles south of Pinole. They saw a 2-engine bomber aircraft pass low overhead to the southeast, then saw far beyond and high above it, possibly one mile higher, a strange fast-flying irregularly shaped translucent white "amoeba" headed east, the size of a 4-engine bomber, with three appendages in front two trailing with a dark grey spot possibly spherical near the center which remained stable in motion, the arms of the "amoeba" undulating, the object wobbling, disappeared suddenly, no trail. Another object sighted: a buff or grey rectangle with vertical lines.
