Actually Dan B, we had to change to the DC10 because of customer requirements. Local guys will/are being hired for line pilots, expats for training/checking and for operations that require US citizenship...in addition to another contract in Africa.
Fifteen local crews initially...only three expat crews required at the moment.
Next question?
Forgot to add, the local guys will be 4 on one off as well, and will expect them to be available for all flights during their four months on, up to the legal limitations.
