According to their statistics;
Decade:NrOfAccidents (Fatal)
1950:158
1960:158
1970:147
1980:151
1990+:156
no big difference but it says more people survives these days if a crash occurs
add: just realised this only took the fatal accidents into that statistics. but anyway, those are the more interesting ones
Decade: %surviving
1930: 18
1940: 23
1950: 22
1960: 21
1970: 24
1980: 33
1990+: 32
also, "Military aircraft and accidents involving private and charter aircraft were not included."
I don't know what to make of it. More sources needed to be sure I guess
