Problematic Roller Coasters

Maverick's removed "heartline" roll was most likely one of the most intense roller coaster elements ever created. In this video, we analyze the physics of the inversion to explain why it was likely removed.

In 1997, Six Flags took one of the riskiest moves in theme park history with their attempt to open four prototype launching roller coasters at the same time. This included the two tracks of Batman and Robin: The Chiller at Six Flags Great Adventure, Mr. Freeze at Six Flags Over Texas, and Mr. Freeze at Six Flags St. Louis. Find out just how big of a disaster this was, and why Batman and Robin: The Chiller unfortunately closed after less than a decade of operations.
