Here is a sure fire way of seeing a UFO. The method used to see them is fairly simple. The theory goes that there are hundreds of objects flying through the sky everyday, as evidenced by George Ritter's hundreds of UFOs at this web site, but they only become visible as they pass through the bright area of sky surrounding the sun, where they become highly reflective. You can't usually see them because the glare of the sun blocks them out.

Therefore, all you have to do is block out the actual disk of the sun, so that you can just see the bright area of sky, wear sunglasses, and watch for a while. You don't need to see the area directly at the edge of the sun (too bright), the clearest objects I saw were about 20 degrees away from the edge. I highly recommend giving this a go. You might feel like an idiot at first, but after about 30 minutes you should feel justified in your actions. A lot of birds and bugs fly past, but after actually seeing a UFO, you come to realize that your eyes aren't that unreliable, and the difference is obvious according to the article.
