This redefined being in the jet-stream. A United Airlines passenger was left “wet and humiliated” after getting soaked by a stream of unidentified liquid aboard a recent flight from Houston to Chicago Sunday, as seen in a viral Instagram clip. “I was soaked from head to undies LITERALLY…embarrassed is an understatement,” Kevin Glover, 39, captioned the clip of the mortifying incident.
