A New Eye in the Sky
Who said anything about landing?
The unmanned surveillance plane that can fly for five years non-stop
It might look like alien technology but this aircraft is no UFO. It's an Odysseus solar-powered aircraft that aims to be able to stay in the air for over five years continuously.
It has a Z-wing configuration that spans almost 500ft (150 metres) so that the aircraft's shape can be adjusted when in sunlight to absorb as much solar power as possible.
Then when it is in darkness, it flies flat in a straight line for aerodynamic efficiency with the energy collected stored in onboard batteries used to drive the aircraft's electric motors. 
Thanks for share good pic...
