A Frontier Airlines passenger was restrained on a flight from Denver to Houston after he allegedly began screaming and punching the aircraft window.
The passenger attempted to speak to a woman in the row in front of him, but she didn't reply. He then lost his mind and started punching the seat in front of him and the plane window. The window sustained damage... cracks and the passenger's blood was on the glass.
He was eventually restrained by another male passnger, who collected shoe laces to use as restraints.
