After years of planning, the solar-powered airplane Solar Impulse 2 has successfully started its round the world trip. If everything goes to plan, it will become the first aircraft to fly around the globe without a single drop of fuel.

It took me a bit to realize this is not an unmanned flight. It has to make something like 12 stops along the way.

Haha, it is only built to go about 88 mph. Its also making multiple stops for PR reasons. The trip is expected to take 5 months!

With that ultra low wing loading and light weight, it would want to stay well away from the jet streams and their associated clear air turbulence. |
