Alpen-Flug was a steel suspended roller coaster built by German aircraft company Messerschmidt. It was the first modern suspended roller coaster and is only known to have operated at Oktoberfest during 1975.
Alpen-Flug was built by Messerschmidt, a German aircraft manufacturer with calculations supplied by Werner Stengel. Since the trains swung anyway, track banking was eliminated as a cost saving measure, despite Stengel strongly advising it. Because of this, Stengel left the project.
The Alpen-Flug debuted at Oktoberfest 1975 and was a fast and thrilling ride however after the fair, the ride was found to have severe structural damage. This was a direct result of the lateral forces created by the unbanked turns. Because of this, the Alepn-Flug and a clone under construction at the time were both scrapped.
Despite the ride having a similar track style to Mind Bender and Shock Wave, Anton Schwarzkopf had nothing to do with this project. In fact, Schwarkopf had only disdain for the ride, thinking that Messerschmidt building this ride would be like his company trying to design airplanes and helicopters.
