This mechanical phoenix that you see here is the Solar Impulse, and this completely solar-powered plane just completed its first flight this morning.
The flight lasted 87-minutes long, and soared to 5,500 feet. During that time, it only achieved a top speed of 44 miles per hour. According to the pilot, Marcus Scherdel, "the aircraft's control-ability matches our expectations".
