Killer Drones in the Empire State
At dusk I stood on a residential street with trim lawns and watched planes approach a runaway along the other side of a chain-link fence. Just a few dozen yards away, a JetBlue airliner landed. Then a United plane followed. But the next aircraft looked different. It was a bit smaller and had no markings or taillights. A propeller whirled at the back. And instead of the high-pitched screech of a jet, the sound was more like... a drone.
