1. Security issue
The most interesting thing is that safety is more of a secondary factor influencing the ban on flights in this zone than a key one. The water area is too large. If some kind of emergency occurs, the crew will have to hard put the car on the water. If at least one of the engines has failed or there is another serious problem, this is of little use.
According to aviation standards, the aircraft must be located at a distance of no more than three hours from the nearest airport to it. This is necessary so that in the event of an emergency, the aircraft has the opportunity to fly and land, thereby saving the lives of the crew and passengers in the case of a passenger liner. Currently, most aircraft are well equipped and are able to travel long distances without refueling. But the risk of danger is higher in any case than flying around.
2. Aircraft flight path
Airplanes do not fly on straight segments, only on curved lines. The reasons for this are quite objective. First of all, it is again a question of safety, both of the aircraft and of people. The path passes through the so-called "air corridors". These are the places where the crew can communicate with the dispatcher at the airport.
This is especially important in emergency situations. If necessary, operators will be able to correct the route, which saves the lives of those in the air. The second point is that pilots need to bypass difficult conditions for movement in airspace. The reason for changing course may be adverse weather conditions.
3. Errors on the map
Standard maps have many inaccuracies. Often the distance between points, which is visible on the map, is much less than the real one. Looking at the graphic image, it seems that the shortest road is a straight line, but in fact this path is the longest.
Errors are natural, since it is almost impossible to place on a flat surface what is shown on a spherical map, while maintaining accuracy exactly. As a result, it turns out that the map deceives for many hundreds of kilometers, and in some cases for thousands. In this regard, it turns out that the closer the plane is to land, the shorter the flight. With rare exceptions, flights through this zone are still carried out.

4. pacific islands
There are several countries in the Pacific Ocean on the islands for which communication with the mainland is vital, so despite all the risks, planes still fly. These countries include Vanuatu, Fiji, Hawaii, Samoa and others.
It will be equally interesting and useful to learn about the wake of an aircraft: how it arises and what danger it poses to other liners.
