We were driving home from ventura headed towards oxnard, we were driving southbound on victoria, when we both noticed a light in the sky zipping by at a very high speed. it was going in a perfect horizontal path from west toward east, never have i seen something travel so fast in the sky, it was completely lit up, with a bright white light and a green tinge, it was going very fast and suddenly it broke off into two separate lights, one continuing in the eastern path at high speed, the other went straight up into the sky, they both then completely disappeared in the blink of an eye. there were no airplanes or helicopters or signs of aircraft around. and there was nothing in the sky the second day disappeared. did not see anything in this guy or in the area immediately after. it was as if it had never been there. it completely vanished it did not fade away or disintegrate. it was as if it just disappeared as if zapped away. the speed in which this ufo traveled was very very fast we could barely keep up with it and it appeared out of nowhere. when it first appeared it went up and then down and then up and then down. then immediately zipped from west to east so fast it was almost like a flash and it was very bright. have never seen anything like it, and i have never seen anything before as far as ufos go. so glad my boyfriend witnessed this also, we both just were in complete shock. we both cannot figure out what we saw. we don't know what it was but we know what it wasn't, it definitely wasn't a flare, an airplane, a jet, a helicopter, a drone or a shooting star, or a firework, or a reflection or street lights, car lights, swamp gas lol, whether this was natural or unnatural phenomenon it definitely is categorized as a ufo in my opinion. a little creeped out still really feeling bothered by this whole thing would like to know what i saw.
