Drones are wonderful. As long as they're not armed like the shotgun-equipped units being deployed in Texas.
I watched a documentary the other day about cave exploration, in what may turn out to be the largest cave system ever found. They used drones to capture some amazing video of parts of the cave no human has ever set foot in.
After that big earthquake in Nepal, there was HD video released the next day showing the devastation from about 100 feet up. Thanks to drones, the world got to see just how bad it really was, people opened their wallets and international aid started coming in right away.
Best of all, Amazon wants to start delivering packages by drone. This, I'm sure, will spawn a new sport: skeet-shooting with prizes!
