NTSB is investigating the crash of Facebook's Aquila internet drone during its test flight in June
@AlanLevin1 More stories by Alan Levin — NTSB investigating aircraft's structural failure on approach — Company founder Zuckerberg called June test flight successful
Context & Ripple Effects
Facebook unveiled Aquila in March 2015 as a solar-powered drone with a Boeing 737-scale wingspan, and its first full test flight in June 2016 was framed internally as a triumph — founder Mark Zuckerberg publicly called it successful. The NTSB's decision to open a formal investigation into a structural failure on approach directly challenges that framing.
The stakes are unusually high for a corporate test program: an NTSB probe subjects a private company's experimental aircraft to the same investigative machinery used for commercial aviation accidents, and the findings will shape whether Aquila's next flights proceed.
First-order effects
- Facebook must now cooperate with an NTSB investigation into the structural failure during landing, putting its engineering data and test protocols under federal review while Zuckerberg's 'successful' characterization is formally tested.
Second-order effects
- The NTSB's eventual finding — that the autopilot failed to compensate for unexpectedly high winds on landing (per its December determination) — forces Facebook to rework Aquila's flight-control software and landing procedures before further tests.
Third-order effects
- If the pattern holds, large experimental drones built by internet companies get pulled into aviation-grade safety oversight rather than treated as product R&D, raising the cost and cadence of every subsequent test flight — a bar Aquila ultimately cleared with a clean second flight in mid-2017.
The trend: High-altitude solar drones are shifting from publicity-driven demo flights toward aviation-grade certification, with NTSB investigations setting the pace for Facebook's connectivity ambitions.
