I first spotted a very bright light that looked like it could be over Liberty when I headed south on 169 just passing the vineyard church. It looked like it was moving really fast in a northeastern direction - but it was going way too fast and it was far too low... There is an airport in that direction so I blew it off but then it stopped dead just a little south of Staley golf course. I thought I was just seeing things and shrugged it off like "they must have put an LTE tower there or something..." and it remained stopped until I got just past the 435 on-ramp to 169.In the time it took for me to make it to the middle of the shoal creek exit, it had covered so much ground, was so bright... and SO low that I was SURE it was a commercial plane about to crash. My heart stopped and I stopped the car at the top of the ramp and rolled the windows down. I was more convinced that it was a crashing plane because I couldn't hear any engine just a "swish" like moving air.Just as I was worried for my own safety because the bright light was so close, it passed over my car and I saw it from the belly side. I realized that there were three of those lights - one on each end of three equally spaced wing-like extensions from a circular middle. My google search for the military aircraft responsible for this experience will now begin...
