What is the main duty of the executive to be recruited? [originaltext] Th

The Wall Street Journal reported recently that Uber put up a job posting for an executive position at UberExpress, the drone delivery operation within its UberEats food delivery unit, to help get the drones up and running sometime in 2019, with commercial drone delivery of food planned in multiple locations by 2021.
        The need for an executive makes sense since Uber is currently a partner with the City of San Diego, which is one of 10 localities that are participating in a federal pilot program to integrate drones into local airspace. Furthermore, the FAA Reauthorization Act of 2018 told the FAA to update the existing regulations, originally designed for manned aircraft, to address under 55-pound drone delivery. Regardless of these two beneficial events, there are at least two major hurdles that UberExpress will face to establish a commercial food drone delivery business: the law and the economics.
        Uber is going to face issues with the federal government as well as the states that the commercial drone delivery services will be offered in. On top of that, some counties, cities, and towns have created laws that could affect the operations as well. For one given flight, you could have federal, state, county, and city laws applying to the flight, some of which could even be contradicting each other!
        From the economic viewpoint, there are two important caveats about using drones for delivery. To keep in mind is that law and safety drive the economics of the aviation industry and operational possibility does not equal operational profitability.
        Although painstaking efforts may be required to clear all these obstacles, I am very much willing to see drone delivery prevailing in the country. And why stop with food? I think UberExpress has the opportunity to expand and provide fast delivery of other low-weight items where availability is an issue, such as medicines or blood to patients with time-sensitive problems.
