What happened

A United Airlines plane bound for Spain from Newark Liberty international airport turned around mid-flight on Saturday due to a possible security threat.

Why it matters

That came one day after another United Airlines flight bound for Minneapolis from Chicago was diverted to Madison, Wisconsin, on Friday because an unruly passenger evidently tried to breach the cockpit.

Common ground

Saturday’s flight departed at about 6pm for Palma de Mallorca, Spain, but landed back at Newark Liberty at 9.37pm, according to the airport’s operator, the port authority of New York and New Jersey.
