Pilot Accidentally Locks Himself Out of the Cockpit [VIDEO]

Having a Pilot behind the controls of a in-flight airplane is just a mundane detail, right? 

This is a video a passenger took after they were notified by the captain that he had just accidentally locked himself out of the cockpit. 9 out of 10 times a pilot is something you want to be in the cockpit but this captain seems to think it's not that necessary for this flight. Because of this issue the co-pilot has to conduct an emergency landing sans the pilot.

I am to understand that all went well and everybody was safe thus making this situation no laughable. also can we take a moment to admire how remarkably calm everyone is when receiving this news? This isn't an episodes of Wings, this is real life and everyone doesn't seem to mind. I love it.
