My girlfriend, friend and i were walking in the park nearby. I saw a light rise up above one of the apartments. Initially i thought it was a comet or something. But this was way to close. I could cleary see a v shaped rear end.. couldn't see the vehicle. But at the rear end was a greenish bluish energy trail. wasn't too long. it was followed by a beam of yellow light behind it. It was a constant beam. perfect edges.. not like a tail of a comet or what not. it started slower.. wasn't slow... it stopped.. then it sped of. we tried following it.. but it just disappeared. like a ship going into FTL on those sci fi series and what not. it seemed like it was taking off from an island amongst all the fjords.
