Myself and two friends were sitting in a car talking.I was distracted from our conversation as it seemed for a moment the reflection of my cigarette in the auto glass was moving strangly,when my friend said "what is that!"I said I thought it was my relection but it is not. We all got out of the car and watched the object pass from right to left then back to the right and the accelerate straight up with a speed greater than any Thunderbird or Blue Angel .We asked each other to confirm what each of us had just seen .We all said exactly the same and no sooner had we all agreed,then the object came back and made a very similar pass, again, leaving by going straight up.There was no doubt the object was real and we all instantly knew it was some sort of craft unknown to any of us.We were very excited and felt fortunate to have seen it.
