I'll try and give some of my findings on this rather gruesome business without belabouring the point. However,in order to be succinct, I'll have to point you to my sources.
However, I have to say a plethora of factors tend to *distort the stats on this topic as most of these type of aviation events go unreported. The factors are not limited to, but include the following:
Classified government information.
Rogue arms trade flights.
Covert Mercenary movements
Smugglers of undeclared precious cargo, diamonds, drugs, etc.
Poor ATC control follow up.
Unless an aircraft is declared missing, ATC hardly have the resources to track aircraft that have filed valid flight plans with intent to just overfly the airspace.
As we are all aware, most of the equipment involved *are Russian and eastern built or some dinosaurs officially removed from service which are sometimes difficult to trace.

The past 5 years have seen the Sudan military alone report over17 fatal crashes, mid-airs, and shot downs. You don't how many are classified and not reported. Evidence point to at least 3 times the number. Fatalities nearly 200. This might give you an idea:
