Solar plane lands after two-week flight


A week ago we reported on the Zephyr solar airplane flying nonstop for a week. Yesterday it landed safely after flying nonstop for two weeks, achieving the goal its designers set for it.

The unmanned drone runs on efficient solar cells along its wingspan that charge batteries to keep it running through the night. Sunny skies over Arizona helped boost its power. Engineers hope that it will be the first “eternal plane”, never having to land. Qinetiq, the UK defense firm that designed it and flew it over a US military base, said there was no need for it to land yesterday but that it had proven its worth and is now ready for production.

The US military is interested in using it for military purposes, but Qinetiq is also pointing up the plane’s scientific and commercial possibilities.

The previous endurance record for an unmanned drone was 30 hours, 24 minutes. A manned solar plane, the Solar Impulse, recently flew through the night on a 24-hour flight.
