In just two years, Google's drone delivery service expects to soar into the American market. Reuters reports that David Vos, the project lead for Google's experimental drone delivery service Project Wing, told an air traffic control conference that "our goal is to have commercial business up and running in 2017."

Though, as some have pointed out, missing from that bold proclamation are the thorny matters of getting clearance from the U.S. Federal Aviation Administration (FAA) if the drones are to operate in the United States, not to mention answers to other questions of technical and legal feasibility. Who pays for damage caused to person, property, or the cargo itself if a drone crashes, for instance?

That said, Google Wing is one of the more exciting offshoots of Google's (ok, Alphabet's) core business of selling ads against online searches. The idea is familiar: a small package delivery service powered by small flying drones.
