Preliminary investigations have revealed that the lives of the 153 persons aboard the ill-fated Dana Air’s McDonnell Douglas MD-83 aircraft, and the six persons on ground, may have been saved if the pilot had turn on certain fuel pumps or valves. According to Associated Press, a United States-Nigerian preliminary investigation blamed the crash on human error adding that the most likely cause of the accident was the crew’s failure to properly monitor fuel flow and turn on certain fuel pumps. The McDonnell Douglas MD-83, operated by Nigeria’s Dana Air, lost power from both engines while approaching the airport in Lagos last June and slammed into an apartment building.
