Telephoned Report: An INS Border Patrol officer called NUFORC to report a dramatic sighting on the U. S.-Mexico border the California desert, approximately 70 miles east of San Diego. At approximately 0530 hrs. (Pacific Standard Time), on Thursday morning, 31JA02, the officer was seated in his patrol vehicle, facing south toward the Mexican border. His dog became visibly agitated, at which time the officer began to discern a warbling sound, which fluctuated in pitch. For a moment or two, the officer thought that the sound was being generated by his vehicle. The officer reports that he was quite surprised to see a disc shaped object, with a noticable bulge on its top, and fluctuating illumination around its flange, fly from west to east, directly above his vehicle. A moment later, the officer looked back to the area of the sky from which this first object had just flown, and was equally surprised to see a cluster of discs, similar in appearance to the first disc, fly across the sky in the same direction in which the first object had flown. In the center of the cluster of objects, the officer witnessed a "boomerang-shaped" object, which he at first took to be a "military bomber." ((NUFORC Note: Presumably a B-2 bomber, which looks like a flying wing. PD))The officer quickly jumped out of his vehicle to get a better look at the objects as they moved fairly rapidly to the east. At approximately that moment, the boomerang-shaped object, the officer reports, suddenly accelerated in velocity, began to rise at a sharp angle into the cloudless, dark morning sky, and disappeared from sight. A short time later, the discs also accelerated, and flew off in the same direction that the boomerang-shaped object had flown. NUFORC hopes to be able to obtain more information about this incident. Audio excerpts of the officer's report to NUFORC, played during the Jeff Rense Radio Program on February 12, 2002, can be heard from the archived radio programs at the website, <www.rense.com>.
