## CONFIDENTIAL
About 65 miles south of Albuquerque 7 unidentified objects flying on northerly heading were observed. Objects initially in V formation at an estimated altitude of 20,000 ft above earth. Formation varied from "V" to "L" to "Q" and then grouped in an irregular formation and a regular pulsating flashing light was observed from them after they had passed 30 $ ^{\circ} $ beyond zenith. The shape was difficult to ascertain. When directly overhead they were circular and resembled a cluster of balloons traveling at a great rate of speed. The color was that of aluminum at high altitude (or white painted aircraft). It the altitude estimation is correct the speed could be estimated as 1500 MPH. There was no vapor, smoke or other trail visible. They did not appear spherical when viewed at oblique angle. Disappeared on heading between north and northwest.
