No dependency on computers necessary for people to do stupid things. We blame automation but incompetence, failure to follow procedures, complacency, and dysfunctional cultural norms (ethnic or professional) are often a major contributor to disasters.
At a desert oil production station (Gialo) in Libya in the 80's a pilot crashed an LAA F27 passenger plane carrying field workers when he attempted a landing on the old runway instead of the new one.
The day was perfectly clear: not a cloud in the sky. Visibility was extremely good. Virtually no wind.
The old runway had been dusted over with crushed white Saharan calichi which made it fade into the surrounding background of light tan hardpan and sand. To further discourage use of the old runway, loads of rock had been dumped in piles down the centre end to end.
The new runway was inline with and off the end of the old. Brand spanking new asphalt, black as midnight, complete with high contrast runway markings and looking like big black stripe on a pale background. A blindman in a snowstorm could not miss the dang thing; it fairly screamed LAND HERE.
The NOTAMs were updated properly and anyone flying into Gialo would see the runway info as the first item.
Nonetheless, the pilot made his usual approach over the station like he had done many many times previous and did not realize the mistake until he was just about to touch down. Pulled up but a wheel caught a rock pile and he pranged the nose into the old strip. Go figure.
No one was killed and as far as I saw, they all walked off. One fella (a Brit of some flavour) had been sleeping and stepped out saying 'What's all the fuss about?". We turned him about and, gazing at the bent props, crushed nose and broken gear, he said: "Felt like a regular landing to me."
