Alphabet has shut down its Titan unit that was exploring the use of unmanned aerial vehicles for the delivery of internet services.
The Google parent is instead focusing on its balloons-based Project Loon to deliver the Internet to remote areas.
Google acquired in 2014 Titan Aerospace and the team from the drone startup was brought in late 2015 into the X research lab, which incubates a number of Alphabet moonshot projects like the Project Wing project for drone-based delivery.
