Yes, doohdave, it's easy to get distracted, or to forget this or the other thing. And that's obviously true for any activity... Pilots are human, after all, and not perfect, godly beings.
The world is imperfect, and risk does exist everywhere. Many people wish to live in a fully riskless environment, but that's basically impossible...
Perhaps only very few modifications are needed, if any. After all, and in spite of some tragic and spectacular accidents, the global safety record of civil aviation is very good.
