Part 3: Executive Summary
The purpose of the visualization task was to analyze the safety of 56 airline companies
across two period, which include 1985 to 1999 and 2000 to 2014. One of the things that stood
out was the number of fatalities reported by China Ailine, Japan Airline, and Malaysia Airlines.
While China Airlines and Japan Airlines reported the highest number of fatalities between 1985
and 1999, Malaysia Airlines reported the highest number of fatalities between 2000 and 2014.
What is interesting about Japan Airlines while it reported the highest number of fatalities
between 1985 and 1999, there was no fatality reported between 2000 and 2014, which marks a
significant improvement. This is unlike only reported 34 fatalities between 1985 and 1999 but
537 between 2000 and 2014.
One of the logical conclusions from the analyses is that the number of incidents, fatal
incidents, and fatalities increases with an increase in the distance travelled. Most of the airlines
with the highest number of kilometers traveled in a week reported the highest number of cases.
This is an indication that incidents and fatalities are a probability whose occurrence can be
explained by the distance covered.
