"Experimental Solar-Powered Plane Takes Flight After 9-Month Delay" [1]
"The experimental plane called Solar Impulse 2 has taken off in Hawaii after a nine-month delay for repairs.
The team on the ground and at mission control let out exuberant cheers as the cutting-edge aircraft rose up into the early morning skies.
They're aiming to circumnavigate the globe using only the power of the sun."
