fire in the skyit was pretty much just a bright star-looking light shining right above some trees. it slowly got dimmer and dimmer until you couldn't see it any more until it suddenly grew brighter and bigger very quickly. it turned a sort of reddish-yellow. basically like a big flame in the sky. it initially took on the shape of a cylindar, but then became more like a cresent moon, as if implying a sphere. After a few minutes at this intesity, it again grew dimmer until it was lost from sight. And like before, it "returned", growing both brighter and bigger once again. it repeated this for about ten minutes before finally growing dim and disappearing for good. my whole family saw it. it wasn't a plane. nor anything else i've ever seen. it wasn't a surprise to me that seconds after it had vanished, a single jet flew directly over where it had been, turned around, and flew away. hmm....
