Jabird, with respect, no one has "answered" anything at all.
Of course there are cases where a jet transport aircraft has landed off airport and most/all have survived, and equally there are cases where aircraft have landed on an airport and all have perished.
This proves nothing whatsoever except for the utterly predictable presence of a bell-curve representing on to off airfield accients on one axis, and survivable rates on the other.
As ever, all variations of each argument are all provable here by the "spot-focused" observer, and no general answer is discernable to the open minded asessor.
As ever in this age of bizarrely distorted rationale one needs to apply a sense of proportion before answering this very simple question.
If you do so then a very simple answer becomes apparent. There have been several, some more successful than others, in some no one has died and in other everyone has. Why is this a surprise, and what does it "prove".
Bugger all, actually.
