This promotional footage for Six Flags AstroWorld combines 1960s historical footage of the Houston amusement park with 1990s footage of the newly opened Batman The Escape roller coaster. The attraction opened on April 24, 1993. It was previously operated at Six Flags Magic Mountain and Six Flags Great Adventure under the name Shockwave. AstroWorld opened on June 1, 1968, as part of the Astrodomain, a development complex owned by Hofheinz. Six Flags bought the park in 1975, operating it until its closure in 2005.
