Houston We Have A Problem

Thanks to an astute passenger who realized something was amiss here the flight was grounded. Yeah well really watching something pouring out of the wing like this. I am hoping everyone and their brother would inform someone that something was amiss. At least if I were on the flight I would appreciate it if they would say something to someone about it. Ring that bell, "uh excuse me miss but is something suppose to be pouring out of the wing like that?"
