Looks like it may be doing some transit photo shoots!
On this route:
EDDB-EGNR
E/CTOT 0846Z - ROUTE N0450F390 BELID2X BELID Y203 HLZ UL980 ETEBO UG9 RKN UB5 SPY UY70 OTBED/N0481F240 Y70 GOLES L975 WAL DCT TORGO DCT KEGUN - ETA 1034Z
the only people who will get a look at it between SPY and OTBED will be other aircraft or maybe a very lucky North Sea rig worker with a good set of binoculars!
