The hot air balloon is the oldest successful human-carrying flight technology. It is in a class of aircraft known as balloon aircraft. On November 21, 1783, in Paris, France, the first untethered manned flight was made by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes in a hot air balloon created on December 14, 1782 by the Montgolfier brothers. Hot air balloons that can be propelled through the air rather than just being pushed along by the wind are known as airships or, more specifically, thermal airships.
Hot air balloons are able to fly to extremely high altitudes. On November 26, 2005, Vijaypat Singhania set the world altitude record for highest hot air balloon flight, reaching 21,027 m. He took off from downtown Mumbai, India, and landed 240 km south in Panchale. The previous record of 19,811 m had been set by Per Lindstrand on June 6, 1988 in Plano, Texas. As with all unpressurized aircraft, oxygen is needed for all crew and passengers on any flight that exceeds an altitude of about 15,000 ft.
In the United States, a pilot of a hot air balloon must have a pilot certificate from the Federal Aviation Administration and it must carry the rating of "Lighter-than-air free balloon". A pilot does not need a license to fly an ultralight aircraft, but training is highly advised, and some hot air balloons meet the criteria. To carry paying passengers for hire and attend some balloon festivals, a pilot must have a commercial pilot certificate. Commercial hot air balloon pilots may also act as hot air balloon flight instructors. While most balloon pilots fly for the pure joy of floating through the air, many are able to make a living as a professional balloon pilot.
If you’re not sure what live wallpapers are, they’re a type of application that works on a mobile device using the Android operating system (like your device!). The application works as a wallpaper – providing the background image for the home screen—but also works as a conventional application since it can provide user-interaction with the touch screen (allowing the image to change dynamically, for example) and access other hardware and software features within the device (accelerometer, GPS, network access, etc.).
**Multiple backgrounds!** Switch up the background as often or as little as you like with user-configurable options.
**Power saving features!** This app uses much less power than typical live wallpapers. It will take a bit more power to operate than a normal wallpaper, but much, much less battery power than the average live wallpaper.
**Super easy to use!** Upon install the app will bring up the options menu and then immediately let you set the wallpaper. No hassle and easy to use!
**Translated to 35 languages!** Do you really, really want to learn Russian? We didn’t think so, but it’s available just in case, in any language your phone can display!
Please note that live wallpapers can’t be set automatically. We’ll bring you to the setup screen where you’ll select the live wallpaper. We’d love to do it automatically but Android doesn’t allow it.
