Recent studies have shown that pilot error contributes to two-thirds of all crashes in commercial airlines. To address this problem, the airline industry has upgraded its training programs by increasing the hours of classroom instruction and emphasizing communication skills in the cockpit. Yet, it is unrealistic to expect such measures to compensate for pilot's lack of actual flying time. Therefore the airline industry should rethink its training approach to reduce commercial flight crashes.
Which one of the following is an assumption upon which the argument depends?
A) Well-designed training programs can eliminate commercial flight crashes.
B) Classroom instruction and communication skills training are not relevant for commercial flight pilots.
C) The number of airline crashes will decrease if pilot training programs focus on increasing actual flying time.
D) Lack of actual flying time is an important contributor to pilot error in commercial plane crashes.
E) Recent studies about the causes of commercial airline crashes are accurate.
