Agreed. In DRC for instance, AirServ provides air transportation for organisations such as the International Red Cross, Doctors Without Borders and a load of UN agencies (WHO, WFP, HCR...). It conveniently allows their pilots to fly (and take a look around) in hot places such as Bunia, Bukavu, Goma and the like while pretending to do humanitarian work...
Nothing wrong with that by the way, just be aware of it if you want to go and work for them...
