'Combative' man restrained by fellow passengers on Frontier Airlines flight after breaking window

A man aboard a Frontier Airlines flight en route to Houston had to be restrained by fellow passengers on Wednesday after he began kicking seats and hitting a window, eventually breaking the Plexiglas, police said. The flight, F9 4856, departed from Denver and was in the air for about 20 to 30 minutes, when a woman asked the man behind her to switch seats, according to passenger Victoria Clark. This man quickly became enraged, profusely kicking the woman’s seat and trying to break the window, Clark said. "I started having a panic attack," Clark told ABC News. "[I thought] it could be a terrorist attack." The man continued to hit the window and was eventually able to break the Plexiglas, passengers said. Without an air marshal on board, flight attendants asked if there was any law enforcement to help, passengers recounted. That’s when Tanner Phillips, a former member of the military, said he stepped in. "This guy was just going crazy," Phillips told ABC News. "He was screaming in multiple languages, punching out the window and laying back and trying to kick it out. I wanted to help as much as I could." Story has details.<br/>
