I'm sorry, did you just suggest we pack explosives in commercial cargo drones as a safety measure? Explosives enough to vaporise 10kg drone plus its cargo. Are we looking at mini nukes here?
In my defence, a quick search shows this story:

So apparently it's not a stupid suggestion and Amazon are thinking along the same lines.
I only ask because it seems making drones land safely is hard. I mean, a paracute with a whistle is a great idea until it drifts in front of a car moving at high speed, or lands on a deaf person or shorts out a high-voltage cable. They all have problems. If there was a way to convert the failed drone into widely dispersed very small objects, the harm may be much lower.
