After nine days and four minutes in the sky, the experimental aircraft Voyager lands at Edwards Air Force Base in California, completing the first nonstop flight around the globe on one load of fuel.

By the time it returned, after flying 25,012 miles around the planet, it had just five gallons of fuel left in its remaining operational fuel tank.
