Bertrand Piccard piloted the plane for a final time, steering it safely from the Egyptian capital Cairo to the UAE. He has been taking turns at the controls with Swiss compatriot Andre Borschberg, with the mission aiming to promote renewable energy. It brings to an end a voyage that began in Abu Dhabi on 9 March last year. "The future is clean. The future is you. The future is now. Let's take it further,'' Mr Piccard said, arriving into Abu Dhabi to cheers and applause.
