Jane, aren't you four months early on this story?
If this really isn't a joke, and one of these flying monsters clips a pet of mine, I'm designing a Flak cannon and selling it as a XBone or PS4 upgrade. It's such an upgrade it doesn't even plug into the console, the console just gives you flight information, and away you go knocking down these godless insects. Not only that, you get prizes, sometimes undamaged, on each kill.
It would make a nice profit, the gamer would get their money back over time, and have great fun. The consumer would figure out there's another way to get items in 30 minutes - there's an invention called a "store". Amazon would lose, but by going on the decadent path, they should.
If you think that's an overreaction, just imagine what happens when one of these things malfunctions and comes down on an animal, tree, or human with some of the blades still twirling. Sooner or later everything malfunctions, and even though the odds of clipping something living are low, multiply it by the enormous amount of things Amazon sells, and will ship this way, and it's simply inevitable something is getting nailed by this monstrosity.
Since Amazon is now using USPS, it's not like using these demons will lessen the amount of driving necessary, since they have to go to every house anyway.
Also, what if birds follow these vile beast? It sure seems confident, and purposeful, and they might decide it's an alpha bird, of some sort. It's a matter of time before Amazon decides it should crow to announce your package, and then all the hens will find it irresistible.
If I see one, I'm shooting it down. Of course, that's after it's delivered my package.
