I was sitting outside looking west at sky, dusk nearly dark. bright flash made me think for a micro second shooting star. i was looking almost straight at it, my eyes focused on 2 side by side bright white lights that flashed on and off very quickly. followed immediately by 2 lights on and off right below. this happened at shooting star speed, total time maybe half a second. whatever the lights were they were falling very fast and seamed pretty close, (half to one mile). lights were too powerful to be a drone. falling too fast to be a crashing aircraft. not hovering, could see no craft around lights shadowed against dusk sky.
