Experience Level1/5
RemarksGAAAAAA! HOW DO I FIND OUT WHAT IT WAS??!! This is the first time I\'ve seen something like this, so I\'m understandably curious. My first thought was that it was perhaps a plane going down (which might also explain the sirens) but there was no burst of light like I would expect with a plane crash.
