Airbus Zephyr Solar High Altitude Pseudo-Satellite flies for longer than any other aircraft during its successful maiden flight
A solar-powered aircraft built by Airbus broke the record for longest continuous flight this week.
If the unmanned Zephyr S had stayed aloft for just three minutes longer, it would have flown for exactly 26 days.
By harnessing the sun’s rays, the drone was able to power its two propellers during the day and store power in its onboard battery unit to be used at night.
At a cruising altitude of 70,000 feet, the aircraft flies well above the level of commercial airliners and inclement weather.
