It turned out to be AC-130J 18-5905 enroute from BIKF via EGUN to Eastern Europe. Apparently this was the first visit of this particular aircraft in the European theatre.
Andrew St Edmunds photographed the aircraft while on approach to EGUN; awesome image!
On 10APR22 a Russian IL96 picked-up several persona non grata in Bruxelles. Because of the sanctions and the flight restrictions the routing of the aircraft was a bit peculiar…
It turns out to be the personal aircraft of the president of Turkmenistan. A bit of an illusive aircraft because not many details are known. However a fellow PP pointed me in the direction of an interesting article:
Boeing 737 EZ-A700 (translated). The original article (including imagery) can be found here.
A rare image of the actual airplane can be found here.
The aircraft apparently landed at KADM this same day after a stop over at probably KPQI. The reason for the aircraft being at the destination is probably for maintenance or upgrades / alterations to systems or the interior.
