There are a lot of reasons that flights make emergency landings. Sometimes it's a passenger's unbearable stench, sometimes people need to poop, and other times sometimes a "quite rowdy" man with a blow-up doll causes such a disturbance that there's no other choice but to kick him off.
That's exactly what happened on a Jet2 flight from Belfast, Ireland to Ibiza, Spain on Friday. This charming man was part of a bachelor party on its way to the international party destination. The man became aggressive toward the flight crew because they wouldn't serve him more alcohol after he'd already been "consuming alcohol illicitly."
What the airline described as "the deplorable behaviour of a particularly disruptive customer" eventually resulted in the plane being grounded at Toulouse airport, where French police were waiting.
