@foxnews: A roller coaster ride takes an unexpected turn at Six Flags Over Texas in Arlington when passengers are forced to climb down a towering staircase after the Titan comes to a stop halfway up its first incline. Video captured by a parkgoer shows multiple riders carefully making their way down the steps of the 245-foot attraction. It remains unclear how many passengers were aboard or what caused the ride to stop. The Titan was previously evacuated in May after a park-wide power outage stopped the ride midair. Six Flags said the ride was inspected, cleared and returned to service shortly afterward.
