Zephyr Solar Plane lands after setting flight record

The UK-built Zephyr unmanned aerial vehicle (UAV) took its place in history by becoming the first aircraft to stay afloat for 336 hours and 24 minutes. The solar-powered craft completed two weeks of non-stop flight above a U.S. Army range in Arizona before being ordered to land.It broke all endurance records for an unpiloted vehicle before it landed on Friday.We are just really delighted with the performance, said project manager Jon Saltmarsh. After only 31 hours of being in the air it took over the record for a long-duration flight by a drone.
