At 4:15am(local Edmonton time)I was takeing a smoke break out side my work when i notice a large round white craft moveing silently an fast over tree tops an town houses.I have no idea what it was .But iam asumeing a ufo. At first i thought it was a airplane flying low due to the rain an lighting at the time.But i notice that this craft was round an white with flashing lights an very large like a jumbo jet..the prolbem with this is that a jumbo jet isnt round an silent,nore dose a jumbo jet fly so very low over peoples homes.i,ve never seen anything like it befor.i watch the local news to see if there was any reports of ufo,s or people reporting seeing ufo,s but there wasnt anything on the news.I wanted to report this but i didnt know who to report this to.Due to the angel of the direction the ufo was going i belive it was heading towards(or near ) Edmonton,s International airport. Iam haveing a hard time excepting what i saw but it was amazing to see it.Iam hopeing other people saw this as well. I,ve allways belived in ufo,s but never thought i would see one for my self.
