When visiting Bergen aan Zee I noticed a Belgian A-109 flying along the coast on a southbound heading. ADSB gave H-27 and it possibly visited Den Helder. Anyone for a confirmation?
I also saw the A109, and a Bö105 along the coast of Katwijk to the north. Destination De Kooy?
That sound I haven't heard for a while
Serial according to ADS-B was RA-02543.
