The NTSB is investigating the ‘structural failure’ of Facebook’s Aquila internet drone

Say what you will about the merits of Facebook’s Internet.org and Free Basics — it’s pretty cool that they’re building a huge, solar-powered, laser-shooting drone to deliver it. But a “structural failure” that occurred on the Aquila’s first test flight may be more serious than Facebook made it out to be: The National Transportation Safety Board is conducting an investigation, Bloomberg reports.

We’ve contacted the NTSB for more information and to acquire the report on the incident, if it exists (these things can take time), but haven’t heard back yet. We’ll update the post when we do.

Facebook wrote about its tests (which occurred on June 28) in July, listing several things they were looking at, learned and so on. Under the “Real-world conditions” bullet point, the blog post admits things weren’t entirely nominal:

We are still analyzing the results of the extended test, including a structural failure we experienced just before landing. We hope to share more details on this and other structural tests in the future.

They didn’t, possibly because of the NTSB investigation, but Facebook did issue a statement today emphasizing the positive outcomes of the test:

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.

Really, it was too much to hope that nothing would go wrong on the first full-scale test of an enormous, experimental aircraft design. A source close to the project told TechCrunch that some damage was expected, since the Aquila isn’t actually designed for repeat takeoffs and landings (it has skids, not landing gear), and also because the day was windier than expected. The failure occurred just a few seconds before landing from the craft’s 90-minute flight, the source said.

It’s the NTSB’s prerogative to investigate any airborne troubles like this, and clearly it decided to so in this case, perhaps because of the high-profile nature of the test and aircraft. But the NTSB wouldn’t get involved if a screw dropped off — Bloomberg reports that the safety organization classified the incident as an “accident,” which implies the damage was “substantial.”

These terms, however, have specific meanings to NTSB investigators and aircraft testers. If the Aquila had nose-dived into the ground, caught fire or sustained some other high-profile damage, that likely would have come out by now. We’re waiting on the incident report for the rest of the information — but considering the scope of the project and pride evinced by Facebook in the Aquila’s development, it seemed reasonable to, well, clip its wings a little bit.
