Facebook says its solar-powered Aquila drone completed its second test flight successfully, flying for 1 hour and 46 minutes before landing perfectly

Context & Ripple Effects
This flight closes out a rough arc for Facebook's connectivity drone. The program was announced in 2015 as a solar-powered aircraft with a Boeing 737-sized wingspan, backed by a full-scale prototype and a 10-gigabit-per-second laser link for beaming data between aircraft. But the inaugural test flight in July 2016 ended badly: the NTSB later determined the drone crashed because its autopilot failed to compensate for unexpectedly high winds during landing.
First-order effects
- Facebook now has a clean end-to-end flight on record — 1 hour 46 minutes aloft and, critically, an uneventful landing, which was the exact failure mode that downed the first aircraft.
Second-order effects
- With the airframe proven twice over, the program's next bottleneck shifts to the parts not yet demonstrated in flight: the 10 Gbps laser interconnect and the long-duration solar endurance the original design promised.
Third-order effects
- If the fix-and-refly cadence holds, solar high-altitude drones move from experimental one-offs toward a repeatable platform class for delivering internet access — with airspace regulators like the NTSB effectively co-authoring the certification path through their crash findings.
The trend: High-altitude solar drones are graduating from prototype stunts to flight-tested infrastructure, with each regulator-reviewed failure feeding directly into the next airframe revision.
