My mother and i were on our way home from the store, when out of the corner of my left eye i saw what i thought was an extremely bright star at first. i pointed it out to my mom and as we drove about another 30-40 feet we were able to see that it definitely was not a star. the object looked black in color(it was at night, but i got a very good look at it despite it being dark out) and had a very big, very bright white light on the front-most point with a red pulsating light on each of the outermost points. we then stopped the car because we were shocked at what we were seeing! at this time, the triangular object appeared to be hovering in one spot, which was over a small marina. we then made a left onto the street next to the marina. from this angle, we were able to see the object more clearly. it looked way too low to be an airplane, the lights were also way too bright, not to mention it was clearly a full triangle shape. we then pulled over again and i got out of the car to have a better look. at this time, the object started to fly in a straight line very fast. it was making a sort of rumbling noise, but it was going so fast (way faster than an airplane) that the sound was actually behind the object (you’d see the object, but wouldn’t hear it right away, like the sound was following behind it). it was almost right over our heads now, permitting us to see the bottom/underneath of it, which had more colored lights on it. it was almost like once it realized we were watching it, thats when it started flying away. once it flew far enough away that we weren’t able to see it any longer, we pulled away and proceeded back home. both my mom and i felt a bit uneasy after the sighting.
