UFOs Are a Common Sight, Former Military Official Tells Congress (Non Paywall in comments)

My theory has always been that these are higher dimensional shapes passing through a 3d membrane. The erratic darting around makes more sense in that context... It's like if you drop a chain into the water, just looking at where it hits the surface it would seem like 2-4 orbs jumping around with incredible speed, but in reality it's not moving in relationship to the surface, so it wouldn't have water resistance except as it falls through the 2d slice

I mean I'd love for these to be aliens, but darting around impossibly is a very strange way to communicate... This also tends to happen around certain regions more than others. That makes sense to me, depending on the hyper geometry I think you'd expect to see

Hell, maybe it is higher dimensional aliens playing with us like we play with fish sometimes, just dropping things in the water and watching us get all excited
