I know this is a contentious issue and skepticism is high on this threads but it's an issue that should not be ignored.
The hobby of astronomy is important in this regard in that we spend hours upon hours closely observing the night sky, usually on clear and visible nights. While I have never seen a so called "UFO," I personally know people who have seen unexplained lights in the sky and aircraft that do not match conventional shapes.
I do not mean to imply that any of these objects are of extraterrestrial origin, although I do not rule out any possibilities of what people are seeing.
I also know that many people are afraid to speak out, especially on forums like this for fear of ridicule, which I think is unfair to honest and open scientific inquiry.
Have any of you or any one of your friends, especially friends of yours in the astronomy community, ever seen a so called "UFO"? If so, what is your story?
Note: I understand that anything we cannot identify is technically a "UFO," but I am specifically referring to any seen object that defies all conventional explanation.
