Reports Report 2908amt (Event 2908-2014)

Observer
Name Gewei Z
Experience Level 3/5
Remarks I wonder at least some pilots or airport staff should also see this. It was quite bright. Looks like something falling out of the plane, but no accident was report when I check news. When I see others reporting fireballs, I think this is very likely a fireball.
