A passenger on a Frontier Airlines flight had to be restrained by other travelers after he broke a plane window.

An out-of-control Frontier Airlines passenger punched an airplane window so hard that it cracked before he was hogtied by other passengers.

Chaos erupted aboard a Frontier Airlines flight from Denver to Houston this past week when a man started bashing a window and several seats around him, prompting other passengers to subdue him with shoelaces and zip ties until the plane landed.
