Is it possible to open an airplane's emergency exit door mid-flight?

A Leominster man allegedly attacked a United Airlines flight attendant and tried to open an emergency exit door. But is such a task even possible?

american captain: situation?
american flight tech: the pressure is six cars or twenty polar bears, sir.

Korean Man who opens the door:

I like how they used polar bears as a weight reference. 😂😂😂😂😅

Boy do they look like shit now that Asiana 214 had its door opened at cruise altitude.

These idiots neglect to understand the 24, 000 pounds is PUSHING OUT on the door, not in! If the guy unpins the door and unlatches those safety bolts… we’ll, you get Asiana 214!
