4AC9AF SE-RMO, no info available yet, although it started out as with an MHS Aviation flight (MHS450) and changed into SERMO during flight.
Could possibly be one of the Dorniers flown for Sun Air of Scandinavia (D-DIRJ, D-CIRI, D-CIRP)
that will enter the Swedish register.
I'll get back as soon as I know more :)
