Tunnel 29
Around 30 helpers, mostly students, dug a tunnel from a factory on Bernauer Straße to a cellar in East Berlin; 29 people escaped through it over two days while an American TV crew filmed.

From early summer 1962 a group of helpers, largely students, dug a tunnel from a factory building at Bernauer Straße 78/79 in West Berlin under the border to the cellar of Schönholzer Straße 7 in East Berlin. Among the organisers were the Italian students Luigi Spina and Domenico Sesta and Hasso Herschel, who had himself fled the GDR.
To finance the work, Spina and Sesta sold the rights to film the digging and the arrival of refugees in the West to the American broadcaster NBC. Some of the diggers distanced themselves from what they saw as turning escape help into a business.
On 14 and 15 September 1962, 29 East Germans crawled through the roughly 120-metre tunnel to West Berlin, among them Hasso Herschel's sister. The escape succeeded without incident, and the number of refugees gave the tunnel its name. Work had been interrupted earlier by water ingress, and the tunnel was abandoned after it flooded.
