I think it's a Farnair Hungary Fokker F27 HA-FAF that does these flights, there's a lot of strange cargo flights operating in and out of the UK at the moment, specially BHX with An-12s, An-26s, Metros, SAABs....all these are on special freight flights supporting the automotive industry...hope this helps
He who laughs last obviously has'nt heard the bad news.
