The first flight of Facebook's Internet drone didn't have a very smooth landing.

Bloomberg on Monday reported that the drone, dubbed Aquila, crashed in the Arizona desert as it was coming in for a landing during its first test flight on June 28. The US National Transportation Safety Board is currently investigating the accident, which was the result of a "structural failure."

No one was injured, but the drone reportedly suffered substantial damage.

In a statement to PCMag, the social media giant put a positive spin on the run, saying "we were happy with the successful first test flight and were able to verify several performance models and components including aerodynamics, batteries, control systems and crew training, with no major unexpected results. We have already learned a lot from the results of this flight test and will continue to learn from all the future flight tests we plan to run."

The incident comes after Facebook recently faced another snafu in its efforts to expand Internet access to underserved areas. In September, a SpaceX rocket exploded on a launchpad in Florida, destroying a Facebook satellite intended to expand Internet access in Africa.

Facebook previously shared some details about the June 28 test flight, during which Aquila remained in the air for 96 minutes at an altitude of 2,150 feet and only consumed 2,000 watts of power.

"To prove out the full capacity of the design, we will push Aquila to the limits in a lengthy series of tests in the coming months and years," Facebook said in July. "Failures are expected and sometimes even planned; we learn more when we push the plane to the brink."

The drone has the wingspan of a commercial airliner but the power consumption of a hair dryer. Facebook says it will eventually fly for weeks at a time, beaming Internet signals up to 60 miles away, though a lot of work still needs to be done before Aquila can serve its intended purpose. At cruising speed, it will consume 5,000 watts of power from its solar panels and batteries.
