We were driving on the freeway on the way home from a high-school graduation ceremony, and the car windows were open. my brother was on his phone (he was one of the high-school graduates), when he dropped it with a yelp, claiming his phone,"zapped", him. i thought he was just pulling a prank, so i wasn't paying attention. instead, i was looking at the buildings out the window. but then i saw something flashing orange. it seemed to just appear out of thin air. the orange light had a pulse, like a heartbeat. and it started getting closer, and as it got closer i noticed it was making a static noise. it stopped about twenty feet away. at that point it stopped glowing, and i noticed an insignia on the chrome surface. i didn't get that good a look because it seemed to vibrate, but it looked like a red symbol, like the chinese use symbols, but this was probably some kind of alien picture language. it was shaped like a 3d oval with a chrome surface. and at first i thought it was some fancy rich kids expensive toy drone but then i noticed that the way it was moving was impossible with even the most advanced drone tech. it would seem to go up 10 feet from it's flat angle of flight in a perfect 90 degree angle, take incredibly sharp turns, and stop suddenly. by the way i would also like to mention in the span of about 20 seconds, when suddenly it flashed shadow, like an octopus squirting ink in the water(but in this case it was in the air, and when the shadowy, inky cloud dissipated, the ufo was gone. and that's my ufo sighting.
