Everything in aviation is a trade-off. The Army can apply $$ and horsepower to the problem. An installation appropriate to an AH-64 is not practical in an ultralight. And the military sends aircraft places where the expectation is for a higher crash rate. Most civilian aviators are much less likely to have an uncontrolled contact with the ground than any military aviator. So the trade-offs are different.

The safest airplane is one that never leaves the ground. But they aren't any fun either.

Best of luck,
