Speigel writes that drone flights have been recorded since August 8, and subsequently, up to four drones were observed almost every night. They tried to track them using police UAVs, but spy drones reach speeds of up to 100 km/h and can cover large distances. In addition to the industrial park, part of which is located on the northern bank of the Elbe, one of the drones was spotted on the southern bank of the river, in the area of the cities of Stade and Balle, this happened on August 16.
