Triangular UFO was filmed during thunderstorm in Pekin, Illinois Witness description: "A triangular shaped object that looked like it was hovering and then ascended up into the clouds. Me my nephew and his father went outside to watch the storm come in. One front had already passed through, and we were watching the second front come in. I could feel the electricity on my skin. I started filming because the clouds were rippled and as soon as I started filming my brother-in-law said what is that! And you can hear us all in shock and excitement as this triangular object ascends into the clouds." https://youtu.be/FGD_LWnonlg
