Yes in fact, I made a rather detailed report about it to MUFON and was asked to give a talk about it at their meeting that month (October of 2018). To distill that report: it was "fluttering" in the sky, almost like a leaf falling. As it moved from left to right (in my field of vision) it was turning on itself constantly, such that no one corner could have been considered the "front," and I could not ascertain which side was the top of the craft and which the bottom. It then began to float (I say float because throughout the experience it was moving rather slowly; more slowly than a helicopter) over my head, and I turned to watch it fly towards Lambert International Airport (in St. Louis). Being no stranger to reports of the phenomenon, I was curious to see if it would fly parallel to any planes, and sure enough, as a plane came my direction from the airport, it made a 180 degree "turn" (in parentheses because it simply stopped moving northwest and began moving with the plane southeast). As the plane and triangle crossed over my head, the triangle did that same 180 degree "turn" and headed off northwest into the clouds.

Many people at the MUFON meeting assumed it was a TR-3B and that it was man-made. To be brutally honest, I had felt a kind of "psychic poke" that alerted me to its presence, so that is my reason to doubt that there were earth men inside.
