Limited infrastructure

The limited infrastructure in Tibet is another reason why planes don't fly over the region. Tibet is a remote and sparsely populated region, with limited resources for air traffic control and emergency services. This means that in the event of an emergency, it may be difficult for planes to get the assistance they need, which could be potentially life-threatening.

For example, if a plane experiences a mechanical failure or a medical emergency, it may be difficult for the pilots to communicate with air traffic control or emergency services. In addition, the limited infrastructure in Tibet means that there are few airports or landing strips in the region, which can make it difficult for planes to make emergency landings.

Another challenge with the limited infrastructure in Tibet is that it can be difficult to access the region in the first place. Tibet is a politically sensitive area, and there are restrictions on who can enter the region and where they can travel. This means that it can be difficult for air traffic controllers and emergency services to access the region and provide assistance in the event of an emergency.
