2021-10-09 - Brandon, FL - Changing

I walked outside to my backyard to let my dog out and looked up at the sky (as I do just about every night) it was a perfectly clear night, no clouds. So the stars were really bright. Then, looking north west just over the trees, very faintly in the sky I saw a (unorganized) group of 7 or 8 lights flying south at high speeds. They appeared to be making a turning maneuver from heading east to turning south. But as they turned, they went from being an unorganized group to a perfectly aligned triangle formation that was in plain view for about 10 seconds going across the sky and slowly became unorganized again and disappeared out of view into the distance. The lights appeared to be very dim as If they were very distant or passing thru thick clouds only to see the glow of light thru the clouds. But it was a completely clear night.

I thought they were jets but They made no sound The lights were also traveling at what seemed to be a very fast speed, judging the distance and small size. And comparing it to the speed of an airplane of equal distance, and size.
