I was driving from los angeles to merced to visit my boyfriend, it was around 1:48am and i had gotten off a closing shift at work. i was about 20 minutes out from the town when i was nearing the merced county highway patrol facility off the 99 freeway. while driving, a huge triangular shaped aircraft flew over the freeway from my right side, with 3 bright lights on the bottom of it. it flew over the freeway and stopped over a field, and hovered for about 30 seconds then all 3 lights lined up in a straight vertical line and the aircraft sped up and away back over the freeway. i noticed the clock on my car was stuck at 1:48am for about 5 minutes, and i had attempted to call my boyfriend at 1:49am but he did not answer the phone. at first i thought it was one of those “speed monitored by aircraft” planes, however the aircraft was large, triangular, fast, and flying really low to the ground. literally no noise came from the aircraft, and i could not believe how bright the lights were or how they moved. i have never seen a plane with such great flight control either, there’s no way a normal aircraft or even jet could stop so smoothly or hover without making a noise. i think it looks similar to the tr-3b military aircrafts people see, and it scares me to think i witnessed a part of a government secret or conspiracy.
