This was the first time I flew the DJI Mavic Air drone after buying it. The location was the Volskpark Friedrichschain in Berlin, it is a park close to where I lived at that time, big enough that the drone would not disturb anyone. In the video you can see how big it is and how well this park lends itself to this type of tests. This was in mid-March 2018. Almost 3 years ago.
