On 16.09.21 our team member Dr. Stefan Mändl presented our UAS SilentOne on a symposium of Wirtschaftsförderung Bodenseekreis held in the Dornier Museum with the famous VTOL Do-31 in front of the entrance. The presentation covered the development and production of VTOL UAS for the inspection of large infrastructure. Around 40 visitors of aerospace economy and politics listened to the presentation and several interesting questions were discussed. The visitors were curious about our new system, the fuel cells and the sophisticated safety concept. Overall our UAS SilentOne attracted a lot of interest and has duly arrived.
