Blimps

Blimps are large, airborne vehicles or balloons that stay afloat by containing a gas, like helium, which is lighter than air. They have a rigid or semi-rigid structure, allowing them to maintain shape and carry passengers, equipment, or cameras. Blimps are often used for advertising, aerial photography, or surveillance because they can hover steadily for extended periods. Unlike airplanes, they move slowly and are steered by adjusting their aerodynamic surfaces and ballast. Their ability to provide a stable platform in the air makes them valuable tools for various observational and promotional tasks.
