So this person really tried to bang down the door to the cockpit on a Delta flight out of LAX yesterday.

The Federal Bureau of Investigation Friday was investigating after a man reportedly attempted to break into the cockpit on a flight from Los Angeles International Airport.

According to authorities, Delta Flight 386 was on its way to Nashville. Video from the flight shows flight attendants and passengers wrestling with the man, tackling him and restraining him.

The big guy, the flight attendant who twisted that fool into a pretzel, said this in big boss fashion:

"He kept banging on the flight door. That's a no-no. The second he banged on the door, it was a wrap."

Alpha energy there, just what you need on a plane when a crazy person is trying to gain access to the cockpit in order to "stop the plane."

These dudes seemed to have taken this in stride, but in all honesty, holy cow, what a scary situation when you're 35,000 feet off the ground!
