Denice, thanks for that - Ouch !
MungoP,
Thanks also for your input, and great word ! Had to look it up, ignoramous that I am.
I get the impression that the UN only use contracters, and local ones at that, which makes it difficult for Europeans to get experience of that kind of work. Have you any personal experience, and/or do you know of any other operators.
Many thanks,
