Solar Impulse Has Made It to Oklahoma

Solar Impulse has chalked up another 1,000 miles in its bid to circumnavigate the globe. The all-electric solar-powered aeroplane successfully flew from Phoenix to Tulsa, Oklahoma landing in the dead of night.

The flight took just over 18 hours, with the aeroplane—under the control of Bertrand Piccard—managing to hit an average speed of just 54 mph. The plane uses 17,000 solar panels on its wing to charge 2,077 pounds of lithium battery, so there’s a lot of weight to carry, hence the slow speeds.

Now the rest of the journey remains: On to New York, Europe or North Africa, and then finally Abu Dhabi, where the attempt started. There’s a little way to go yet.
