I encourage you to see a movie, Whisky Romeo Zulu, from Enrique Piñeyro, former pilot of LAPA. The movie has its name as it was the LAPA plane, LV-WRZ
I don´t know if there is any version of it in English, but those who know spanish will appreciate it.
The case of the LAPA plane was not only about pilots forgetting to put the flaps/slats and not giving attention to the TOWS (that in that case worked fine).
It infoms precisely the many layers of swiss cheese that were aligning in that company that lead to the disaster.
Besides all, we are forgetting the particular circumstances of that day, the copilot in charge of the take off knew that he would be fired or offered an administrative work; also a press comunicate from the sindicate pronouncing some facts about the risk in the operations in Spanair (that never saw the light as a consecuence of the accident)...
