Six Flags Over Texas General Manager Steve Calloway is going up the tower of power. After running the Arlington park for 11 years and adding rides like the Titan, the Superman Tower of Power, Batman: The Ride and Mr. Freeze, Calloway has been promoted to oversee special projects for the theme-park chain. "I will have the opportunity to be creative and work with new teams to develop other parks so they are providing superior guest experiences," he said. "I'm looking forward to going in and making contributions at other parks."
