Has the Op actually clarified what it has accounted for in its contribution to being a dangerous airport ???
It seems an air-craft incident unrelated to the airport itself may also count...
From the OP..
"The danger and ranking of airports are determined based on multiple factors, including altitude, wind patterns, runway length, location, as well as social, political, and volatile events".
"It seems an air-craft incident unrelated to the airport itself may also count..."
No, that does not seem to be the case, there is no suggestion of that at all.
