A survival test.to the next step

Everytime when mishap happens, we learn something new and we change and prepare and revise. As we look at into the birth of flight, millions have died, each time, our invention gets better and safer. History is a database of experience of life avoiding the repetition of the same mistakes so that we improve and moves higher in levels of understandings of the unknown factor. It is very complex and complicated if we look from the level of individualism, even in that level, there is something new to learn and explore and we try to understand the meaning of this madness of accidents and death.
