The story behind the Facebook drone crash, can the Aquila drone be revived?

In June, Facebook flew a huge unmanned drone in the Arizona desert. The drone's wingspan exceeded the Boeing 737. In this test, the drone stayed in the air for more than 90 minutes, after which it crashed.

According to a report released from the US National Transportation Safety Board on Friday: Facebook drone crashed and was badly damaged.

The story behind the Facebook drone crash, can the Aquila drone be revived?

The reason for the failure may be due to strong winds. At that time, the aircraft lifted the aircraft above the flight path before landing, causing the autopilot controller to lower the nose and accelerate when the aircraft landed.

According to the report, the turbulent landing caused serious damage to the right wing of the Facebook drone, but fortunately no one was injured and the ground was not damaged.

The Facebook drone should only fly for 30 minutes during the first test run. But because the flight progress was so smooth, the engineers decided to extend the drone test time to three times the original time - a total of 96 minutes. Facebook CEO Mark Zuckerberg also said in a blog post in July: "Flight happens in the early morning, just as the sun begins to rise."

During the extra flight test time, the sun gradually rises and the temperature rises. Yael Maguire, who is in charge of the Facebook Connect Lab, said that during the last four seconds of the flight, his team noticed changes in local temperature and unexpected airflow, but none of them were encountered in the simulation.

According to Friday's blog post, Facebook immediately reported to the National Transportation Safety Board that the drone failed to land. But the company was banned from revealing any information about the crash until the regulator completed the report.

Facebook said that they are already upgrading the Aquila drone, and it will be equipped with a new brake system to help the autopilot land more smoothly.

In the end, Facebook hopes that the Aquila drone can fly for 60 to 90 days at a time because it is powered by solar energy and does not need to be refueled.

The Aquila drone is not Facebook's first project to provide an Internet connection for areas that lack reliable access to the Internet. The company also runs Free Basics, a zero-level, limited Internet version that Facebook will offer to users in 53 countries and cities around the world for free.

However, earlier this year, Indian regulators banned Free Basics and claimed that the service violated network neutrality because it only had access to specific websites.

According to the Internet.org website, the homepage of the Facebook Free Basics project, anyone can add their website to this platform, as long as they follow Facebook's rules to "optimize the performance and adaptability of their website on older mobile phones." Slow network connection. But Facebook is still the goalkeeper of this project.

When Zuckerberg first shared his ambitions for Aquila, he said it was only part of the Internet site.
