@abc7chicago: Cell phone video captured several passengers restraining a man on a Frontier Airlines flight from Houston to Denver. But what happened before those dramatic moments is what scared Victoria Clark and her grandmother, Charlotte Jones. "The lady in front of the gentlemen asked to move seats, and right when she did, he started kicking profusely and started punching the window," Clark said. The window was hit so hard that the plexiglass covering it broke. "He was scary," Clark said. Our sister station in Houston was told the flight attendants went on the intercom to see if any law enforcement personnel were on board.
