Me and my mates were playing basketball on beutiful summer day. The sky was blue and there were no clouds to be seen anywhere. One of my friends looked up and said he saw something so we all looked up (about 10 of us) and there was something that looked like a verticle metalic cylinder just crusing across the sky. I'm gonna repeat that it was a clear blue sky. After a while we started loosing interest (it was a good game) and we started playing but one friend kept looking on and told us it had dissapeared. We all looked up again and the UFO, as it is at the moment, was gone.
