At approximately 10:50 PM as I was leaving the Spinx gas station in Irmo, SC. As I turned right going towards a stop light I saw what I thought at first to being an airplane flying low. I thought wow that awful low to still be a good ways from the airport. As I kept staring at it I noticed it wasn't moving. Sitting stationary. I immediately freaked out as I knew this wasn't normal. I stopped at the light. It was red for a short duration of time. One car was in front of me. I was screaming to myself, what in the hell is that! Oh my god. It's not moving. It's a triangular shaped (almost like a a b2 bomber) with two bright white lights in the side. And some tiny lights more towards the center. I drove under the stop light and still it was sitting in the same spot. I drove under it. The car in front brakes a few times but went on. I pulled my car immediately off the side of the road so I could look back and see it. I got my phone out and started up snapchat. At exactly that time I head what sounded like plane engines throttling up. And as I started to raise my phone it was now moving and gaining speed fast. Like a dummy I threw my phone back in the car and proceeded to try and chase after it to get a better video. I was driving down Woodrow Street and it was moving over the trees flying over St. Andrew Rd. I sped up so I could clear the trees and see it again but by the time I reached a clearing it was nowhere to be found. Gone. Vanished. I'm not a UFO believer. I'm not sure what it was but I know for a fact it was sitting stationary for a duration of time. That's not normal. And then it takes off and reaches speeds I can keep up with. I feel like I'm losing my mind. I have no reason to make up stories. I haven't the time. But this compelled me to come here and share my story. Who knows what it was that I saw but I sure will think twice about UFOs. Seriously the scariest and strangest thing I've ever seen. Would love to know if planes were flying low altitude over Irmo, SC tonight. But what explains the hovering? Why couldn't I have just thought to capture the video at the stop light! I'm beyond frustrated. Wow, I believe I really just saw UFO. Crazy. Would love for the people in the car in front of me to come foward. I know they saw it as well.
