Correlations among the demographic variables

It comes as no surprise that captains have more total flight hours (14,718) and more automated hours (3,251) than first officers (9080 and 2814) (p<0.01 by t-test and Wilcoxon nonparametric tests). They also have more, but not significantly more, time in the 757/767 than the first officers have (2811 to 2533). See table 1.

Pilots with no military training have significantly more total hours, more time since training, and more automated hours than pilots with airforce training have (All p< 0.05 by the Scheffe's test). See table X. Similarly, pilots with Navy training report more time since training, more automated hours, and more hours on the 757/767 than pilots with airforce training (All p< 0.05 by the Scheffe's test). It may be important to keep this in mind while interpreting the findings that follow. Contrary to the general perception in the industry, the ranks of less senior and less experienced pilots at this airline are not loaded with pilots who lack military training. This airline seems to have been drawing on pilots without military training for some time.
