archos,
no it's just that having a lot of nationalities, there have often been factions when there have been large numbers of one nationality like (in no particular order of preference or anything) Brits, Portuguese, Indians, South Americans. Some have been more favourably treated by management than others in the past and doubtless that will continue until CHC makes any changes in the management hierarchy.
I also heard from a friend that somebody brought a couple of Bell 407s into Lagos without doing anything like getting permission. Apparently they've been impounded for being illegally imported. Anybody in Lagos heard anything about that?
