We all know the old maxim put around :UFOs can't exist as astronomers who spend so much time looking skywards never see them.well tonight I saw something I cannot I explain! I was not really stargazing just walking home from the rail station after a long trip and I saw how bright Jupiter was so decided to sit on a bench and admire it using a 8x25 monocular I was packing. Across the field of view flew 3 objects like luminous balls and one was weaving in and out of the others.sadly I was under a tree and couldn't track them higher into the sky due to the branches. It was a most extraordinarily thing and I really cannot explain it.birds? But why was one weaving out of the others which where going straight also don't think large birds fly at night plus they where luminous (swans or white geese I suppose could appear luminous?). No definitely not satellites due to the erratic formation flying. Planes?no noise and why would they be doing it at 0100hrs!?then again why would aliens put on air displays?closest thing I can think of is the foo fighters allegedly seen by ww2 air men. I must say it unnerved me a bit.
