Ziplines and cables
Sliding or climbing hand over hand along a line stretched above the border strip.
A line fixed high on both sides carried people over the whole border strip at once, and in Berlin that strip was typically about 70 metres wide.1
The method is rare, and every case on this site worked differently. On 27 December 1962 the circus artiste Horst Klein tried to cross the Teltow Canal along a high-voltage line at the Späthbrücke; he lost his strength, fell onto the eastern bank and was fetched by West Berlin firemen in a rubber dinghy. On 28 July 1965 the Holzapfel family from Leipzig hid in a top-floor toilet of the Haus der Ministerien, the East German government building beside the border, until it emptied, climbed onto the roof after dark, threw a nylon line weighted with a hammer to helpers on the western side and slid down a steel cable of about eight millimetres, fixed to a flagpole and anchored 100 to 120 metres away. On 31 March 1983 Holger Bethke and Michael Becker shot a line over the strip from a Treptow tenement with a bow and arrow; Ingo Bethke, who had fled in 1975, secured the cable in the West, and the two rode over on home-made wooden pulleys.
In the mid-1960s the GDR tore down several buildings along the border to give its guards an unobstructed view and a clear field of fire.2 The three cases here used structures that still stood close to the line: a power line across a canal, a government building and a Treptow tenement.
