Qinetiq’s Zephyr solar powered high-altitude long-endurance (HALE) Unmanned Aerial Vehicle (UAV) has flown a world-beating three and a half day flight at the US Army's Yuma Proving Ground in Arizona. The solar powered plane flew for 82 hours 37 minutes, exceeding the current official world record for unmanned flight which stands at 30 hours 24 minutes set by Global Hawk in 2001 and Zephyr's previous longest flight of 54 hours achieved last year.
