Recently, X tested delivering burritos from Chipotle to students at Virginia Tech. The move was arguably little more than a publicity stunt, given that current regulations require a drone pilot to keep a drone within his or her field of view the entire time it’s flying. That means that setting up a delivery network, where drones fly out on their own to deliver goods a few miles from their location, is impossible. The FAA has indicated that in the future, it would may update and adapt the regulations that it put into place this year to allow autonomous drone deliveries. But the air-traffic control system it has tasked NASA with building isn’t due to be shown to the FAA until 2019.

In the meantime, X’s project has had some issues, erm, taking off. Vos left the project in October, and according to Bloomberg, hiring was frozen on the project and members of team were asked to look for jobs elsewhere. Project Wing had also been working on a deal with Starbucks to test delivering coffee, but the partnership was called off, after disagreements over what Starbucks customer data Alphabet could have access to, Bloomberg also reported. Whether this certificate will help Alphabet get closer to its goal of drone deliveries remains very much up in the air.
