By Louis Charbonneau and John Irish VIENNA (Reuters) - Iran and world powers continued marathon talks on Saturday in an attempt to clinch an historic nuclear accord but remained divided on issues such as lifting U.N. sanctions and development of advanced centrifuges. Diplomats close to the negotiations said they had tentative agreement on a mechanism for suspending U.S. and European Union sanctions on Iran. "We don't have Iran on board yet." Senior Iranian and Western diplomats echoed the remarks.
The Solar Impulse 2 aircraft completed a historic flight in its quest to circle the globe without consuming a drop of fuel, touching down gracefully in Hawaii on Friday after the most arduous leg of its journey. The sun-powered plane, piloted by veteran Swiss aviator Andre Borschberg, took 118 hours -- about five days -- to make the voyage from Japan to Hawaii and landed shortly after dawn at Kalaeloa Airport on the main Hawaiian island of Oahu. "Just landed in #Hawaii with @solarimpulse! For @bertrandpiccard and I, it's a dream coming true," Borschberg tweeted triumphantly after completing the most perilous part of the around-the-world odyssey.
