The flying accuracy of a Hot Air Balloon may be adversely affected by changing natural conditions such as wind, air density, altitude/temperature, humidity and time of day. Special precautions should be taken to ensure safety when working in any extreme temperatures or terrain, e.g., mountains and deserts. Manmade conditions such as weight, weight distribution and/or the discharge of pyrotechnics in close proximity can also affect the balloon’s ability to fly.
