Bertrand Piccard and Brian Jones become the first to circumnavigate the Earth in a hot air balloon.

Bertrand Piccard FRSGS is a Swiss explorer, psychiatrist and environmentalist. Along with Brian Jones, he was the first to complete a non-stop balloon flight around the globe, in a balloon named Breitling Orbiter 3. He was the initiator, chairman, and pilot, with André Borschberg, of Solar Impulse, the first successful round-the-world solar-powered flight. In 2012 Piccard was awarded a Champions of the Earth award by the UN Environment Programme. He is the founder and chairman of the Solar Impulse Foundation.

Brian George Jones is an English balloonist.

Circumnavigation is the complete navigation around an entire island, continent, or astronomical body. This article focuses on the circumnavigation of Earth.

A hot air balloon is a lighter-than-air aircraft consisting of a bag, called an envelope, which contains heated air. Suspended beneath is a gondola or wicker basket, which carries passengers and a source of heat, in most cases an open flame caused by burning liquid propane. The heated air inside the envelope makes it buoyant, since it has a lower density than the colder air outside the envelope. As with all aircraft, hot air balloons cannot fly beyond the atmosphere. The envelope does not have to be sealed at the bottom, since the air inside the envelope is at about the same pressure as the surrounding air. In modern sport balloons the envelope is generally made from nylon fabric, and the inlet of the balloon is made from a fire-resistant material such as Nomex. Modern balloons have been made in many shapes, such as rocket ships and the shapes of various commercial products, though the traditional shape is used for most non-commercial and many commercial applications.
