Remember that in the early days, crashes were often caused by mechanical malfunctions. Clever design and improved skills in building has minimised those incidents. Now, it is the human that is lacking.
Yup, I agree Mr. Swede. You hit the nail on the head.
Airplanes these days are pretty damn idiot proof and reliable, but us being humans, we can still cock it up, and we do. Coltan, AF, Bolivian RJ 85 and many others.
None of us are bullet proof. Had a few close calls being fatigued and too greedy to call it quits. My bad, and a bit of luck.
One learns from experience, sadly these low-time guys who crashed the mail flight in Sweden were just hanging on, not much experience to learn from and the Luck Bucket went dry.
R.I.P. Gentlemen and to the rest of you rookies: Pay attention and get ready for a high tech airplane wanting to kill you: Stay one step ahead and be slightly paranoid.
