The noise

Today me and my friends heard an unexplainable noise while we were at the park. The park was silent as it was a school day for kids with finals and lower grade kids. The animal controll was at the park along with a police officer. At around 1pm we heard a loud noise that appeared to be comming from no where.
It was a loud metalic noise and we went home to look something up on it, there were a few videos and reports about other people hearing it up in the northern hemosphere.
However when my parents tried to get more information on it all they got were tru tv sites etc. In the end me and my friends may sound like crazy babbling idiots but we know what we heard so be on your toes and keep your ears open!
