Question

Among fatal plane crashes that occurred during the past 65 years, 374 were due to pilot error, 51 were due to other human error, 659 were due to weather, 565 were due to mechanical problems, and 90 were due to sabotage. Construct the relative frequency distribution. What is the most serious threat to aviation safety, and can anything be done about it?

Answer 1

Mechanical problems since they can be solved and have the second most deaths. I would have the plane go through at least 3 examinations before boarding then one passenger exam before takeoff.
