In like 2003 my sister and I were driving home through a big stretch of country and we saw a fucking huge ass disc with lights around the edge jet up from the tree line and disappear into the clouds at an extreme speed. I don't think it was aliens but damn I sure will always wonder wtf that thing was.
I always wonder if those instances are super high energy particles ionizing air. If they travel fast enough, you'd basically see everything all at once and it would look crazy.
Like imagine someone throwing a glowing bouncy ball at a window and how it would look first traveling at you then ricocheting off the window and into walls you can't see.
