In the world of aviation, safety is the number one priority; thus, airplanes are designed and equipped with various precautionary measures. For instance, plastic all-weather carry cases, fiberglass containers, or canvas holdalls that store life rafts are supplied on board. Life rafts are incredibly handy during some over-water operations and incidents, ensuring that passengers and air crew can be evacuated with ease.

As aircraft operate at high altitudes, they must be pressurized or have breathable oxygen provided for the safety of passengers and aircrew alike. If such heights pose safety risks for humans, then why do we fly so high? First, airplanes at high altitudes consume less fuel for a given airspeed than they do for the same speed at lower altitudes, making it more efficient to soar high. Second, bad weather and unprecedented turbulence can be avoided by flying in the smooth air above dangerous weather patterns closer to the surface.
