9 Ingenious Smuggling Machines That Beat the Berlin Wall

30 years ago today, the Berlin Wall fell. But long before that, amateur engineers modded machines to escape the grip of the Soviet Union.

November 9, 2019, marks the 30th anniversary of the fall of the Berlin Wall, the physical embodiment of the Iron Curtain separating East and West in the Cold War. The Wall was built in 1961 to stop East Germans escaping to the West, but thousands found ways to beat it, using modified cars, a zipwire, and other feats of backyard engineering. Outside Berlin, intrepid escapees built their own submarines, a balloon, and even a microlight to overcome the wall.

The Berlin Wall comprised two concrete barriers separated by a "death strip," which was 160 yards wide and covered by border guards with Kalashnikovs. Almost 300 people died during escape attempts, but over five thousand got through and many of their ingenious smuggling methods are on permanent display at the Mauermuseum — Museum Haus am Checkpoint Charlie, Berlin, the Berlin Wall Museum next to the former Checkpoint Charlie.

Here's a closer look at these ingenious smuggling machines.

Wolfgang Engels was a 19-year-old driver for in the East German Army in April 1963. His escape was not the best-planned, but it was certainly one of the most daring. He befriended some soldiers who drove SPW-152 personnel carriers and persuaded them to show him how to drive one. When his new friends were on a meal break, Engels stole a getaway vehicle and motored across Berlin.

As he approached the wall, Engels gunned the 110-horsepower engine and rammed the wall at full speed with the ten-ton armored truck. The vehicle’s nose punched through the wall, but it stopped there, with the door on the wrong side. Engels got out and tried to climb over but was caught on barbed wire. An East German Guard fired at him and Engels was hit twice, but West German police returned fire and a group of men piled out of a nearby bar and helped the injured Engels to freedom.

In 1984, Czech Ivo Zdarsky built his own aircraft to fly over the Iron Curtain. A microlight based on the two-stroke engine and fuel tank of the ubiquitous Trabant. Other components were scavenged or home-made.

After taking off at 3 am his homemade propeller struck a rock during take-off but survived thanks to its steel edge. Zdarsky stayed low to avoid radar, flying under power lines and landing at Vienna International Airport. After his escape, Zdarsky moved to the U.S. and set up Ivoprop, a successful business manufacturing propellers.

One way of smuggling a passenger across was in a secret compartment in the car. The included an outsize fake fuel tank, and this BMC Mini with a concealed space for a small person inside the passenger seat.

Back in the early days of electronics, audio equipment providing options for concealment for refugees flexible enough to pack themselves in. Successful escapes were carried out in this old-fashioned wooden radio case, and in the outsize speakers carried by a touring musician.

Roof racks also came into play. A single large object might be too obvious, so one West German found a more subtle way to get his East German girlfriend over the border. By hollowing out two surf boards and putting them together, he created a space just large enough for her to fit in for the short journey across the border.

Balloon

One of the most famous escapes involved a hot air balloon put together by mechanic Peter Strelzyk and bricklayer Günter Wetzel. The balloon was carefully engineered to provide enough lift to carry the two men and their families. The burner was a modified propane tank; the envelope was a stitched-together patchwork of synthetic taffeta in different patterns.

This was bought at several different shops to avoid arousing suspicion. On September 16th, 1979, the two men, with their wives and four children, ascended to a height of eight thousand feet—high enough to avoid East German searchlights—and made a terrifying 25-minute trip. The balloon fabric tore towards the end and Wetzel broke his leg on landing, but all made it safely to the West.

BMW Isetta

The BMW Isetta, better known as the ‘bubble car’ was a 1950’s design classic. Just seven and a half feet long, it took 30 seconds to get up to 30 mph from a standing start. Far too small to smuggle a hidden passenger out under the eyes of the border guards–unless you were a very smart mechanic.

In 1963, Klaus-Günter Jacobi converted his Isetta over several weeks, moving the storage box behind the seat up four inches and welding it back in place, removing the air filters and spare tire to make more space, replacing the rule tank with one the size of an old can, bending the exhaust pipe – then sanding it all down and leaving no trace. Then 5-foot-7-inch Manfed Koster could just squeeze into the hiding space. The border guards did not bother checking such a tiny vehicle, and Jacobi drove right through with his concealed passenger.

Micro-Submarine

Bernd Boettger was an engineer and water sport enthusiast who decided to make his getaway by water, crossing the sea to Sweden in 1967. It was too far to swim unaided, so Boettger built his own underwater tug, a micro-submarine. Normally such tugs would be battery-powered, but like all East Germans, Boettger had to work with what he could get. He constructed his vehicle around a 2-stroke engine from a powered bicycle, with a rubber snorkel tube to get air.

After an initial failure in which he was captured and spent three months in prison, Boettger made a second attempt and crossed 15 miles of water to freedom. He later went on to work on gasoline-powered underwater tugs for commercial divers, which are still sold under the name AquaScooter.

In May 1963, Austrian Heinz Meixner drove up to Checkpoint Charlie in a fancy British sports car, a bright red Austin Healey Sprite convertible. The top was down, and Meixner had made one important modification to the car: he removed the windshield. When the border guards ordered him to pull over for inspection, Meixner lay flat and hit the accelerator. Without the windshield, the entire car was low enough to slip under the lowered barrier. Meixner made it across—along with his East German fiancée hiding behind the seat and his prospective mother-in-law in the trunk.

Norbert Konrad pulled off the same trick a few months later in the exact same car, but the East Germans then added steel bars under the barrier arm to prevent a third attempt.
