Flyoneday,
Welcome to the "prune"...many people here are very insensitive...
Having flown extensively in Africa, including in and out of Douala whilst based there, (working a contract for SAFAIR on behalf of Cameroon Airlines) yes there are problems, but unless one has been there and is prepared to cope, then their opinion of things they know nothing about shouldn't be voiced on a thread such as this.
A new A/C, a well trained crew, and pure speculation...
My symapthy for the loss of your crewmember friends and the pax as well...
