On September 14 Volocopter made its urban flight debut at the Mercedes-Benz Museum in Stuttgart. The flight demo was a part of the event “Vision Smart City — Experience future mobility today” held during the weekend. The flight lasted near 4 minutes at about 30 meters altitude.

One noticeable thing was the low noise level of Volocopter which claims 65 decibel at 75 meters. This noise level is comparable with small helicopters’ noise level at 500 meters and is about the same as the background road noise in urban environment.
