See my reply to Dash 8 for Kenya.
748 services is based in Loki, but operates outside OLS(Operation Lifeline Sudan)the UN umbrella of Ngo's operating into Southern sudan.
They operate, or did as of last December, two Andovers ex Nzaf.
They have their own camp in Loki, very nice quarters with a good bar.
The contacts are Kevin Ashley and Jeff Bartel, both ex UNWFP staff.
