Solar drone with jumbo jet wingspan broke a flight record—then it crashed

Flight Tracking and Ditching

The Skydweller drone was last visible on the flight‑tracking service Flight Radar 24 north of Cancún, Mexico, in the early morning hours of May 4. The company described the drone as eventually performing a “controlled water ditching” around 6:30 am Eastern Time, but the aircraft “subsequently sank due to its non‑buoyant composite structure.”

Record‑Breaking Flight

By the time it went under, the Skydweller drone had completed a solar‑powered flight of eight days and 14 minutes, longer than any previous flight by either a drone or a crewed aircraft. Skydweller Aero called the aircraft an “operational prototype” that had “validated the practical military utility of a persistent, medium‑altitude solar aircraft,” despite the loss at sea.

Historical Context

The aircraft’s earlier accomplishments will likely endure in the public imagination. Solar Impulse 2 became the first solar‑powered aircraft to circle the globe after a series of flights between 2015 and 2016. Along the way, it set a world record for the longest flight in a solar‑powered plane when André Borschberg piloted it for 117 hours 52 minutes—almost five days—during a 5,545‑mile (8,924‑kilometer) journey from Nagoya, Japan, to Hawaii.

Impact of the Crash

The crash means the Swiss Museum of Transport in Lucerne will not receive the historic aircraft, contrary to an original agreement with Skydweller Aero, according to SWI Swissinfo. This represents a blow for aviation enthusiasts unless future salvage operations can be carried out.

Future Outlook

The pioneering design may still inspire future solar‑powered aircraft for civilian or military use. Skydweller Aero told Ars Technica that it has no other prototypes ready to replace the lost drone, but the company’s blog post described “planned upgrades using existing technology” that could enable future solar‑powered drones to better withstand extreme weather conditions.

Meanwhile, the Pentagon has proposed investing at least $54 billion in drone warfare systems, as reported by Ars Technica.
