A historic moment for Solar Impulse 2

<p>The plane will now be flown across the United States and eventually, if all goes according to plan, land back in Abu Dhabi next March, where it started its journey earlier this year.  The next leg will be piloted by Piccard and will fly 2,920 miles from Hawaii to Phoenix. Solar Impusle 2 has 17,000 solar cells and on-board rechargeable lithium batteries, allowing it to fly through the night. Its wingspan is longer than that of a jumbo jet but it weighs only 2.3 tonnes — about the same as a car</p><p>(Photo Credits: AP)</p>
