Tomi Lahren: Final Thoughts on Sunday Kneeling by NFL Players

Greg Gutfeld reflected on the heroic actions of the passengers on United Airlines Flight 93 on 9/11/01.

"Flight 93 was the bravest act I've ever seen," he said.

Shortly after Todd Beamer of Plainsboro, N.J. yelled, "Let's roll," the passengers stormed the cockpit, forcing the plane down in a field in Somerset County, Pa.

Without the heroic actions of the passengers and crew, the plane was said to be aiming for the U.S. Capitol.

Gutfeld said the heroes' actions are a "lesson on how to deal with all challenges."

"It relegates all challenges to their appropriate place in the universe," he said, calling "let's roll" the "model response" for anyone facing hardship.

By thinking of them, "You turn their powerful act into a powerful tool to grab in times that are tough for you," he said.
