Rubber rope launches with gliders took place on Rigi as early as the 1950s. After 2013 and 2015, the Gliding and Flight History Foundation wanted to practice this traditional type of launch with gliders again from this historic, central location, which is also equally easy to reach for all participants. What was technically feasible in the 1950s is still feasible today. Gliders are normally pulled into the air by motor aircraft. Due to this not being possible, alternative types of launch had to be used in the past, such as the rubber rope launch. A rubber rope is attached to the hook on the nose of the glider and around ten people - so-called "rubber dogs" - pull on both ends. As soon as sufficient tension is reached, the holding rope is cut and the aircraft rolls off. Due to the relatively low speed achieved, this type of launch is only suitable for vintage gliders.
