Bright ball of light seen flying above us no more than 50 feet away in Calgary Alberta.I was playing basketball out in Abbeydale this evening and it was getting dark. It was quite cloudy and you coudlnt see any stars. I was with 2 other friends, and I passed the ball to one of them for him to shoot. As I did, i turned the other way and looked at my friend who was looking up. I looked up as well and saw a white ball of light that was gliding across the sky with such perfection. This lasted for about 3 seconds, and then the light seemed to fade away really quick, as if the light scattered across the sky. I have seen meteor showers, and this looked nothing like it. Whats scarey is that It was so cloudy, that if this ufo was above the clouds we would not see it. I could tell that the object was no more than 50 feet above us when if flew by. The way it moved is undescribable. It moved in a straigh line, but with perfection. It was so bright, but did not have a tail behind it. It was so close to us though, and it did not make any noise as it floated across. Whats also very wierd is that there is a sighting posted by a man from Calgary in the January section on this sight. His sighting is very similar to ours, and whats really odd is that he saw it exactly one month before we saw ours. (His sighting occured January 17th, ours was February 17th) One other thing I should add is , the reason I have the exact date AND time of the sighting is because my cell phone rang as soon as we witnessed the object, and my phone recorded the time and date of the call.
