Answer & Explanation:
There are no cameras showing the outside of the plane on long-haul flights in the USA simply because the airlines have not installed them. Airlines have different policies and preferences when it comes to the in-flight entertainment systems in their planes. While some airlines have installed cameras to show the outside of the plane, others may not have installed them to prioritize other essential features such as seat comfort, safety, or cost. Moreover, adding such cameras may require additional equipment, installation, and maintenance costs, which may not be feasible for some airlines.
In addition, some airlines may have concerns about passenger privacy and the potential for cameras to become embezzled. As a result, US regulators may have stringent protocols for such in-flight camera installations that airlines deemed impractical.
Overall, the decision to install cameras showing the outside of the plane on long-haul flights is an individual airline decision, and it depends on various factors such as their customers' preferences and cost decisions.
