This day could see the first visit of an Ukrainian Airlines Antonov An-148. Should be UR-NTA.
The aircraft, flying PS901 which should have arrived at 12.15 LT, is already delayed to 13.30 hrs though...
Flight PS902 should have left Brussels back to Kiev at 13.05 hrs local, but of course this will not be possible now...

EDIT: does that thing fly at all? Again a 737 will fill in as it went tech (again)...
