Went out for the Thai A320SL with the COP26 delegation that flew home via Cologne-Bonn. 2 November 2021 Köln-Bonn 20.30-21.20 D-HVBO EC.135T-2+ Bundespolizei, BPO140, ADS-B, overhead runway, 21:10 Correct, that was also there but as I see them pass overhead daily I sort of forgot about that one :-)
