But how many airliners have landed off-airport without the result being a controlled crash?
I normally fly at 2-3000 feet; airliners fly at 30k plus. This gives them a much greater chance of there being an airfield within gliding distance, assuming it's over a land-mass when the failure occurs.
I normally fly over rural Wales, where to be honest I would hope to survive a forced landing with my life, but be quite surprised to fly the aircraft again.
