Mark Six-
CHC Nigeria has as of about a month ago (at least) the following qualified expats in the 139 (there are 3 machines, not 2). These are just off the top of my head and the amount of time in type varies widely from just above zero to several hundred hours. All, without exception, are 5000+ hour pilots.
1 Aussie
1 Kiwi
1 Austrian
2 Canadians
1 American
1 German
2 Portuguese
1 French
1 Malaysian
1 Indian
1 Namibian
One American who is still with CHC has left Nigeria.
And of course, there are a similar number of Nigerian pilots in the 139.
