As people have said before, the decision to fly or not to fly is entirely yours, and also said is there have been no new ways to hurt ourselves in aviation, and a huge majority of accidents are human error, even on an airliner level more so these days, so as tragic and sad as we all are right now, im sure Ross would be up there telling us all to learn what we can from this experience to make our flying safer. I have lost friends to the stall spin on final, and others to the impossible turnback after EFATO. Unfortunately when considering how many fall victim to these types of accidents, its evident to me that our training isnt quite hitting the mark, so i personally, after previous accidents, and again after this one, took measures to make sure i am as safe as possible, by doing an advanced aircraft control course, including spinning and basic aerobatic maneuvers, and once i get my Savannah in the air again, i will do a refresher, and also concentrate on the EFATO scenario.
fortunately progress has been made into what makes a highly skilled and knowledgable pilot make the decision to turn back, and yes, it goes deep into human factors, and into the subconscious to the flight or flight response to a perceived or real danger. a lot of good people are working on finding the causes and ways to alter training to prevent such accidents occurring again, sadly, they will, but with sublte changes to training, hopefully they will become far less of an occurrence.
Next time you go for a fly, instead of just going on a sightseeing tour, how about practicing some emergency procedures? take an instructor if you want to, or make it a personal minima to practice a forced landing every 4th flight, or an EFATO scenario at least once on every second circuit session you do.. Hopefully Ross's legacy will be better trained, better prepared pilots.
