WebFinally, the high density of the atmosphere at low altitudes brings up the possibility of flying an airship (that is, a powered lighter-than-air vehicle) at low altitudes.12 Since the wind velocities decrease as the surface is approached, only moderate amounts of power are required for propulsion. This will require not only a high-temperature gas WebAbove every square inch on the surface of the Earth is 14.7 pounds of air. That means air exerts 14.7 pounds per square inch (psi) of pressure at Earth’s surface. High in the atmosphere, air pressure decreases. With fewer air molecules above, there is less pressure from the weight of the air above. Pressure varies from day to day at the Earth ...
