DUS: THU 06-07-2017 - Cobrex Trans B737-300 + Mahan Air A340-600
IRM100A EP-MMF airborne just now. ETA around 2120L. So they will probably be able to make it into DUS, but not out again today. At least I assume they won't receive an extended night flight permission (anyhow, even with an arrival at 2051L a departure before 2159 seemed almost impossible for me ).
So possibilities are most likely a nightstop or diverting to CGN.
