Dec. 12, 1948. Starvation Peak near Bernal, New Mexico. 9:02 p.m. ±0.5 min (MST). Dr. Lincoln LaPaz, USAF Capt. Charles L. Phillips, and CAP intelligence officer Lt. Allan B. Clark, returning from green fireball investigations while looking to the NW saw a green fireball at least stellar magnitude -4 traveling E to W low above the horizon about 3°-4° elevation in almost perfectly level flight until the last 0.1 to 0.2 sec when it slightly curved downward, disintegrating into 3-4 pieces, no sound. Based on independent witness, an AESS guard at Los Alamos, LaPaz triangulated object's flight path at about 8-10 miles height along a 25-mile path, speed 39,000 to 43,000 mph. (FOIA)
