With all due respect, I think I have to gently disagree with the idea that:
"Any landing you can walk away from.........." Every time if it's a UAS
These systems are justified as the cheaper, better alternative to manned aircraft. They won't be cheaper if they keep piling in at this sort of rate. Nor will they be better if they're not available because they've piled in.
I've looked at the loss rates for UAVs (UAS, RPAS, drone, etc) and they don't look all that clever. I just hope that when we buy this sort of kit in the future we factor in a realistic attrition rate. Even more important as they get less cheap.
Best regards as ever to those working the cost models,
