re costs and safety, why when a car hits a tree without apparent reason the blame is put onto a drunk or asleep driver and no investigation on mechanical failures is performed?
true, only a few people die in a car accident, but overall, the death rate is massively higher than on commercial aviation.
commercial aviation but not only is already subjected to a massive amount of regulations to enforce high levels of safety.
currently, the safety of commercial aviation is ridicolously high; on a liner you have more chances of dying of natural causes than of accident.
be aware that the search for total safety sparing no costs (like creating huge flat areas around runways) will ultimately decrease death rates statistically, when people will stop flying because they cannot afford it any more.
