As I mentioned a few pages earlier, impulsive acts without understanding the overall risk may lead to other tragedies.
About a mile south of this bridge, in the same river valley, is an unmarked zip line at Camp Kern. It has been hit by an airplane at least once, killing a pilot and his passenger.
The zip line operator has also posted warnings at local airports regarding planes passing near or under their zip line during operating hours.
Not sure if Martha (or others) were aware of or evaluated other obstructions with squishy kids dangling in harnesses like here.
