'When we started the Aquila program back in 2014, very few companies were involved in this area - and they were all working independently of one other.
Aquila's history at Facebook was mixed.
He said: "It's been exciting to see leading companies in the aerospace industry start investing in this technology too - including the design and construction of new high-altitude aircraft".

Facebook has officially dropped a plan to build and launch autonomous drones to bring internet connectivity to now under-served communities, having been working on the project since 2014.
Aquila's aim was to bring internet access to the estimated four billion people living in areas of the world where the infrastructure isn't in place to offer it. Facebook's idea was to utilize a high altitude platform station (HAPS) system to fill the gap.

Increasing innovation in HAPS connectivity efforts has meant that Facebook's planes were failing to meet the long flight times managed by similar projects from rivals like Google's Project Loon, which used high-altitude balloons instead of drones. Facebook based Aquila on the work of the UK-based drone research company Ascenta, which Facebook acquired in 2014-incorporating the operation into the company's Connectivity Lab and Internet.org project.
"Going forward, we'll continue to work with partners like Airbus on HAPS connectivity generally, and on the other technologies needed to make this system work, like flight control computers and high-density batteries", Maguire added. Almost two years later, Facebook has canceled the project.
