A balloon is a type of aircraft that remains aloft due to its buoyancy. A balloon travels by moving with the wind. It is distinct from an airship, which is a buoyant aircraft that can be propelled through the air in a controlled manner. The "basket" or capsule that is suspended by cables beneath a balloon and carries people, animals, or automatic equipment (including cameras and telescopes, and flight-control mechanisms) may also be called the gondola. Following Henry Cavendish's 1766 work on hydrogen, Joseph Black proposed that a balloon filled with hydrogen would be able to rise in the air. The first recorded manned flight was made in a hot air balloon built by the Montgolfier brothers on November 21, 1783. The flight started in Paris and reached a height of 500 feet or so. The pilots, Jean-François Pilâtre de Rozier and François Laurent d'Arlandes, covered about 5½ miles in 25 minutes. Only a few days later, on December 1, 1783, Professor Jacques Charles and Nicholas Louis Robert made the first gas balloon flight, also from Paris. Their hydrogen-filled balloon flew to almost 2, 000 feet (600 m), stayed aloft for over 2 hours and covered a distance of 27 miles (43 km), landing in the small town of Nesles-la-Vallée. The first aircraft disaster occurred in May 1785 when the town of Tullamore, County Offaly, Ireland was seriously damaged when the crash of a balloon resulted in a fire that burned down about 100 houses, making the town home to the world's first aviation disaster. To this day, the town shield depicts a phoenix rising from the ashes. Balloon landing in Mashgh square, Iran (Persia), at the time of Nasser al-Din Shah Qajar, around 1850. Jean-Pierre Blanchard went on to make the first manned flight of a balloon in America on January 9, 1793, after touring Europe to set the record for the first balloon flight in countries including Belgium, Germany, the Netherlands and Poland.
