A Delta Airlines flight was forced to make an emergency landing in the US after a pilot became locked out of the cockpit, according to airport officials.
The Md-90 plane was flying from Minneapolis to Las Vegas, when the cockpit door malfunctioned at midday on Thursday, Sky News reported.
The first officer quickly took over the controls, and safely landed flight 1651 and its 168 passengers and crew at McCarran International Airport in Las Vegas.
Airport spokesperson Christine Crews said that the incident had been taken "very seriously".
The captain later explained to the passengers what had happened.
