Translucent silent triangle craft went right over me

I was in town to play a concert at Guanabanas restaurant and was waiting to go onstage at the outdoor venue. While backstage I was staring at the night sky which was already looking eerie to me so much so that I was taking pics and videos of what I thought might be UFO’s far away in the sky, 3 bright lights perfectly aligned in the sky, left, center and right, but miles apart. I thought they could maybe be planes but I was stunned by how perfectly aligned and steady they were. If they were planes they would eventually get bigger but they all 3 just hovered for a long time. I took more video and after a few minutes I lost interest and figured it had to be planes or 3 perfectly aligned bright stars like Orion’s Belt but much much further apart, if you were on a beach looking at the water, the left light would be all the way left to where you would have to turn your head left to see it and same with the right light. They were pretty far apart but perfectly aligned. Anyways I turned my camera off and literally looked up for about 10 seconds and then suddenly and without any sound at all, a giant translucent triangle maybe the size of 2 Cessna planes flew right over me at tree top level, incredibly close and silent. It had no lights, and nothing solid that I could see as far as a physical body with paint, it was just a completely see through triangle structure that had a greenish tint to it but I could see the clouds through it as it went by me. I tried to grab my phone and take a picture but it had already passed over me and I was in a grove of palm trees and couldn’t see it anymore once it passed. I know there are street cams and beach cams within a block that had to have captured it, as it was flying so low, right above the palm trees and it’s north Miami pretty much, let alone private cameras from businesses and residents. It absolutely blew my mind and I have no idea what it could have been. Perfect triangle shape. Flying slowly but too fast for me to get my camera out of my pocket. It didn’t change color so much as it just was translucent and kind of just became the color it was against, dark blue in the night sky but then I could see the clouds through it so it was white in spots, then as it passed changed back to the night sky blue. It blew my mind.
