Today the solar-powered electric airplane Solar Impulse () made its third test flight:

It’s clear that this project depends heavily on good PR, these flight movies are works of art. If I’m not mistaken this was the first flight where the streamlined cockpit canopy was mounted, and this flight was used fly this airplane a bit more aggressive than before to further test its flight characteristics.

According to the commentary the team expects to be able to fly a complete day-night-day cycle (where the plane flies on solar energy during the daytime, simultaneously charging it batteries, and flying on its batteries by night) within one or two months.
