When military intelligence began investigating Arnold's sighting in early July (see below), they found yet another witness from the area. A member of the Washington State forest service, who had been on fire watch at a tower in Diamond Gap, about south of Yakima, reported seeing flashes at 3:00 p.m. on the 24th over Mount Rainier (or exactly the same time as Arnold's sighting), that appeared to move in a straight line. Similarly, at 3:00 p.m. Sidney B. Gallagher in Washington state (exact position unspecified) reported seeing nine shiny discs flash by to the north.
