United Airlines flight UA858 from Shanghai to San Francisco erupted into chaos shortly after takeoff when a passenger went berserk.
As reported by the NY Post, the Boeing 777-300 had spent two hours in the air when the disturbance began. A video posted by a passenger on the same flight shows cabin crew intervening as the Chinese-speaking passenger allegedly began throwing all the documents in her seat pocket into the air, began screaming curse words, and hitting herself.
