SEE IT: Penn State-Abington professor arrested for ranting, smoking on Nicaragua-Miami flight

She couldn’t save it for the lecture hall.

A Pennsylvania college professor got arrested for launching into a recorded rant about U.S. relations with Venezuela halfway through a flight from Latin America.

“The United States has declared war on Venezuela! The United States has declared war on Venezuela! Venezuela has been declared a national security threat!” Penn State-Abington professor Karen Halnon yells in one clip that went viral.

The sociology prof, who also lit a cigarette on the plane, was unapologetic about the uproar when speaking with the Daily News.

“I found it urgent to speak up against the aggression in Venezuela,” said Halnon, 52.

“If you have to shake up a few people, they need to be shaken up.”
