The Wing company, a Google spinoff, has won federal approval to operate its drone delivery system as an airline in the U.S. Wing hide caption The Wing company, a Google spinoff, has won federal approval to operate its drone delivery system as an airline in the U.S. The Federal Aviation Administration has certified Alphabet's Wing Aviation to operate as an airline, in a first for U.S. drone delivery companies. Wing, which began as a Google X project, has been testing its autonomous drones in southwest Virginia and elsewhere. "Air Carrier Certification means that we can begin a commercial service delivering goods from local businesses to homes in the United States," Wing said in a statement posted to the Medium website. The company has touted many advantages of using unmanned drones to deliver packages, from reducing carbon emissions and road congestion to increasing connections between communities and local businesses. "This is an important step forward for the safe testing and integration of drones into our economy. Safety continues to be our Number One priority as this technology continues to develop and realize its full potential," Secretary of Transportation Elaine L. Chao said in a statement from the agency.

Waymo is the first among dozens of companies testing self-driving cars in California to persuade state regulators its technology is safe enough to permit them on the roads without a safety driver in them. An engineer still must monitor the fully autonomous cars from a remote location and be able to steer and stop the vehicles if something goes wrong.

Lawyers for Google spin-off Waymo are depicting Uber as a conniving company that relied on stolen trade secrets to catch up in the race to build self-driving cars. Uber's attorneys are brushing off the allegations as trumped-up claims designed to thwart a rival.

Now, Waymo is trying to thwart that effort by persuading U.S. District Judge William Alsup to block Uber's self-car driving expansion on the grounds that it hinges on a high-tech heist. The case's outcome could alter the race to build self-driving cars that may transform transportation, reduce traffic deaths and launch a huge new industry.
