The Trudelturm (Spin-Tower) is a about 20 meter high former special wind tunnel to simulate the dangerous state of spin of airplanes in the laboratory. The tower is no longer in use and is currently part of the Aerodynamic Park on Humboldt University’s Adlershof campus. During a stay in Berlin, I finally implemented my long-cherished plan of photographing and post-processing him according to my ideas.
