Yep I had a run in with Helog, many years ago. when they first wanted pilots for the sudan operation, a few people I know actually went. They had one old 330 in green not in UN colours, that sat on the ground for most of the time, the pilots did about 50hrs in six months, where then helog lost the contract, or all the pilots left. says something when the chief pilot walks in on the first day and said to all the co-pilots "those of you who do not have 1000hrs pic in your log books, come back tomorrow with it in there"
I had a lucky escape
