By the end of the1920s, Munich’s Oktoberfest had established itself as a major attraction.Carnival rides had existed there for more than a century, but these were yet tobe systematically inspected.
Since the designs were increasinglydaring and dangerous, the Bavarian Ministries of External Affairs, InternalAffairs and Agriculture and Labour issued a decree in the summer of 1929: TheBayerische Revisionsverein shall regularly inspect the “flying structures” insouthern Bavaria.
In 1930, three of the association’sengineers were deployed at the Oktoberfest to inspect three roller coasters,three toboggan slides and one “motorway” track for weak points. Through therecurring work at the world’s biggest fair, the Munich-based engineersdeveloped a unique, leading expertise in the area of mobile structures, whichis still in demand worldwide to this day.
