"I imagine he perhaps regrets taking him on the rally in the first place"
I doubt that either. A huge fee was involved. From what I can make out, Sam still has that.
Maurice has said on his Facebook that he has been asking for a copy of flight plans from Sam. Maurice infers that his troubles in Sudan have been brought on by lack of paper-work from Sam ?? Maurice also goes on to say the reason for him signing-up in the first instance was because he didn't want the hassles of the paperwork.
"I have been critical of Maurice in the past, and I hold no particular torch for him. However I have spent the last three hours on the phone to various well connected friends"
Well done Terry
