First International Solar Plane Flight is a Complete Success
The 300 mile flight took the Impulse about 12 hours, traveling at about 25 miles per hour, at an altitude of just under 12,000 feet. The one seater aircraft is similar in size to a large plane, but weighs the same as a sedan automobile. The wings are covered with 12,000 solar cells which absorb the sun’s energy, and in turn charge batteries that power the four propellers which are run by the 10-horsepower motors.
