triangular shaped 3 lights incredible from north to south low to very high altitude aircraft event about 1 min. long.Went outside at 10:25 friday nite 19th of december 2008, and looked uo to see the stars after a 4 day rain spell, and out of the blue appeared 3 shining lights similar to sparkling star or prisma, forming a triangular shape. Either could of being 1 unit or maybe 3 airbonre crafts in a tight triangular navigation formation, this appeared zooming from north ( u.s.a. border 1/2 mile)bound south in a straight path.At first, it looked like some kind of helicopter, but then gain tremendous altitude, as well as the speed of this thing was nothing we've seem around here (naval blue angels air station and u.s. air force air station at not more than 30 miles from mexicali). Difinetly not familiar aircraft, since it went out of sight disappearing at an incredible speed. All this took place in only about a minute.Afterwards I inmediately told this to my bussiness associate since we were working late that night, thanks to his advise, here's my ufo report....Merry Christmas to all you folks.
