September 23, 1948 — Santa Fe, NM
9:40 a.m. At Los Alamos National Laboratory, New Mexico, a group of people are waiting for an airplane at the landing strip when one of them notices something glint in the sun. It is a flat, circular object, high in the northern sky. The appearance and relative size is the same as a dime held edgewise and slightly tipped, about 50 feet away. [Eberhart]
