the ufo was triangular in nature..hollow in the middle and very large. It hard lights round it and it was just gliding. we were three witnesses thast saw it and it was a very exihilrating event. My girlfriend looked up and said guys isn't that a shooting star? so me and my buddy looked up and then we just saw the triangluar object gliding so low. there was no noise for how low and HUGE IT WAS. we had goosebumps and we were all screaming wtf is that. it was like a 10 second view..it glided above us and i tried to tape it but it was too short of a view. we were in lethbridge alberta canada on my balcony cause my roof has a balcony on it. If my girlfriend hadn't said that we should look at the shooting star we probably wouldnt have seen it..it was silent..just gliding and it looked hugeeee...UFOS ARE REAL PEOPLE
