An experimental Facebook drone is now the subject of a federal safety investigation after a structural failure caused it to crash.

But Facebook isn鈥檛 letting that hiccup define the project as a failure.

The drone, which is named Aquila and has the wingspan of a Boeing 737, experienced a 鈥渟tructural failure鈥� while approaching Yuma, Ariz. during a test flight last summer, a spokesman for the U.S. National Transportation Safety Board told The Wall Street Journal. No one was injured.

The drone is part of Facebook鈥檚 Internet.org initiative, which aims to bring wireless connections to areas around the globe that lack sufficient internet service. While the crash resulted in structural damage to the drone, the company says the test flight was a success, leading them to extend the duration from around 30 minutes to 90.

鈥淲e 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,鈥� a spokesperson for Facebook told Bloomberg in a statement.

The crash isn鈥檛 the only roadblock Facebook has hit with its free internet initiative. In September, the company sought to launch a satellite into space that would bring internet access to various parts of Africa, but an unexpected explosion destroyed the equipment. The company has also seen pushback from India, which rejected the company鈥檚 offer for free internet services that would have centered around Facebook.

Still, the project may have found favor in Indonesia, and officials have asked if the Aquila drone could be used to beam service to parts of the nation.

"If we make the right investments now, we can connect billions of people in the next decade and lead the way for our generation to do great things," Facebook CEO Mark Zuckerberg said in a Facebook post after the Asia-Pacific Economic Cooperation summit in Peru on Saturday.

The NTSB is continuing to investigate the drone crash and plans to release a full report within the next few months. The company has designed the drone to use solar energy and battery power to fly for months at a time, allowing it to deliver data 10 times faster than current models.

If the drone continues to see success, Facebook plans to build an entire fleet of similar models to deliver internet to more than 1.6 billion people in rural areas. 聽鈥淲e gathered lots of data about our models and the aircraft structure 鈥� and after two years of development, it was emotional to see Aquila actually get off the ground,鈥� Mr. Zuckerberg said in post after the flight.
