Drones are machines that are usually used to bring internet services over to rural areas or to those places that don't have an internet connection. Google informed the public that they shut down their own drone project.
According to reports, Google's parent company, Alphabet announced that they shut down the drone project called Titan. The company shut down the project in early 2016 after it faced technical difficulties and financial problems. There's no actual reason for Alphabet to cancel the Titan drone project but it could be traced back to some of the accidents the drone experienced back then.
Back in 2015, the team in-charge for Titan's development experienced a crash with their drone during its flight in the Arizona Desert. According to reports, the crash is caused by a fault in the wing of the drone. There are other reports of drones crashing during its test flights. On June 28, 2016, Facebook's own Aquila drone crashed, which prompted an investigation with the US safety agency.
Google first acquired the Titan Aerospace back in 2014 after beating Facebook in the bid. According to Google, the drones could help bring internet access to millions of people and may aid in disaster relief operations when the time comes. They also said that it will pose as a helpful tool in battling different environment issues. Later in 2016, Titan is absorbed by Google X due to Alphabet's reshuffling. Since the Titan project is now shutting down, Alphabet advised those who are working for the project to start looking for other jobs within the company and Google itself.
Some of the employees who worked at the Titan project are dispersing to another project called Project Loon effort. The project also shares a similar aim with the drone project; distributing the internet to millions of people but instead of using drones, they'll be using high altitude balloons.
