The case is described by [Tagesschau](https://www.tagesschau.de/investigativ/ndr-wdr/drohnenabwehr-120.html), citing the findings of WDR and NDR radio stations. The event was due to happen on 1 December, so only 2 days after the base reached its first operational readiness. At least 3 drones of an ‘unknown type’ have been spotted that were circulating above the radar strategy at 100 metres.
