Hot air balloon sea level, and humidity of the air surrounding. On a warm day, a balloon cannot lift as much as on a cool day, because the temperature required for launch will exceed the maximum sustainable for nylon envelope fabric. Also, in the lower atmosphere, the lift provided by a hot air balloon decreases about 3% for each 1,000 meters (1% per 1,000 ft) of altitude gained. Standard hot air balloons are known as Montgolfier balloons and rely solely on the buoyancy of hot air provided by the burner and contained by the envelope. This style of balloon was developed by the
The Red Balloon film, with added prose. The book was highly acclaimed and went on to win 'A New York Times Best Illustrated Children's Book of the Year.' Albert Lamorisse was credited as the book's sole author. A soundtrack, featuring music adapted from the film by Lamorisse, was released on the Nonesuch Records label. The Red Balloon The Red Balloon () is a 1956 French fantasy comedy-drama featurette written, produced, and directed by Albert Lamorisse. The thirty-five-minute short, which follows the adventures of a young boy who one day finds a sentient, mute, red balloon, was filmed in the Ménilmontant neighbourhood of Paris.
