Seen Air Forces Monthly this month? Go to the attrition page and look at the Israeli C130 that was opened up by the No.4 engine Prop coming loose!! I would never sit between the red lines that say "Danger Propeller Blades!!!"
I take it that the Airships deem it too risky to have the same thing happenig to the new J fleet. The solution is to take the damn engines off and turn 'em into gliders. It's all so clear now!!!
