Ngiye ngezwa osomkhathi bekhuluma ngokujwayelekile kokuphambuka nezingozi ezihambisana nakho. Kuyini ukujwayeleka kokuphambuka, futhi ngikugwema kanjani?
Ukujwayeleka kokuphambuka kwakuyigama elaqanjwa isazi sezenhlalo uDiane Vaughan owaba nengxenye ekubuyekezweni kwenhlekelele ye-Challenger. Kamuva kwaba isihloko sezinkulumo eziningi zomphakathi ezenziwa ngumsomkhathi uMike Mullane. Ngokuyisisekelo, lo mbono uthi lapho samukela ukuphambuka esilinganisweni esilindelekile, ukuphambuka kuba yisilinganiso. Enhlekeleleni ye-Challenger, onjiniyela baqhubeka beqaphela ama-o-ring enjoloba abuya ekuhlolweni esesimweni sokungabekezelelani. Ngenxa yokuthi kwakungekho ukwehluleka okuphawulekayo phakathi nokuhlolwa, onjiniyela balungisa indinganiso ye-o-ring ukuze ihlanganise lezi zinto ezingavamile. Ngeshwa, ngokujwayeza ukuphambuka ezindinganisweni ezazilindelekile, kwaholela ekwehlulekeni kwe-o-ring ngesikhathi sokwethulwa kwe-Challenger, futhi isikebhe esincane i-Challenger sahlakazeka lapho sisendizeni. Ukujwayeza ukuphambuka kuyisicupho esibalulekile okufanele sigwenywe lapho kuqhutshwa noma iyiphi inhlangano, kodwa ikakhulukazi leyo ebeka amalungu ayo ezimweni ezinobungozi obukhulu, njengokuhamba emkhathini. Ukuze uyigweme, kumelwe ukhumbule, noma ufunde, ukuthi izindinganiso ezithile zasungulwa kanjani nokuthi kungani zasungulwa futhi unamathele kuzo, ngisho nalapho ucindezelwa kakhulu.
