Some went over, others went under and some went right through it!
In a hot air balloon
In 1979, eight people soared over the Berlin Wall in a home-made hot air balloon created with small pieces of nylon cloth. To avoid looking suspicious, the families of Hans Strelczyk and Gunter Wetzel secretly collected small amounts of cloth over a long period of time. After their escape, the East German government began to strictly control the purchases of light-weight cloth.
