Zephyr S, Airbus’ unmanned High-Altitude Pseudo Satellite (HAPS) system, is on course to break a flight endurance record for an aircraft.
The solar-powered aircraft departed on its maiden flight from an unspecified location in Arizona on July 11, 2018. It remains airborne.
Earlier this week, the Zephyr S surpassed the previous flight record for remaining airborne without landing and refuelling, which was 14 days, 22 minutes and eight seconds.
The final endurance record will be confirmed on landing.
