No drones
The harbor master himself thinks that it is an exercise of the Air Force, whereby combat aircraft are refueled in the air. “Due to the prevailing wind, as in this case a north wind, these contrails (cloud stripes, ed.) Can then be blown in inland tens to hundreds of kilometers, so that they suddenly become visible above the interior.”
NH therefore calls Major Abma of the Air Force. In the first instance, she confirms that an exercise has indeed taken place above the Wadden Islands. “A tank plane has flown a pattern at 18000 feet. That could explain this.”
But when she sees the pictures of the circles, the story becomes different. “We have not been this,” she says. “The laps are too small for that. The tank plane has flown more in a bathtub shape.” She doesn’t know what plane is responsible for this. “We don’t know sincerely. In any case, they are not drones.”
