Hot air balloon 3D model

Aerial sightseer, also known as a hot air balloon, is a type of aircraft that lifts off from the ground and travels through the air by using heated air to rise. The craft has an envelope or a gasbag which contains hot air that makes it float high above the earth's surface. A burner, fueled by propane, produces flames that heat up the surrounding air inside the balloon, causing it to expand and grow larger in size. As more hot air is added, the balloon lifts off the ground and begins its ascent into the sky.
