Why don't airplanes fly over Mount Everest or the Pacific Ocean?

🌟Everest

The average height of the Himalayas is over 20,000 feet.

➡️Above a certain height the boundary of the stratosphere layer ends.

➡️Therefore there will be lack of oxygen.

➡️Also at such a height it is rare to get radar & communication with control room on earth.

🔆 This is one reason.🔆

➡️Another is that Indian security forces are engaged in security areas along the Himalayas bordering India.

➡️They have the right to shoot down anything that appears to be an obstacle to their safety, even if it is an aircraft.

➡️Flying over Everest is also not allowed due to security reasons.

🔆Pacific Ocean🔆

The Pacific Ocean is vast.

➡️Approximately 1/3rd of the Earth is covered.

➡️Flying over the Pacific Ocean has also been banned.

➡️In particular, mysterious areas like the Mariana Trench are located in the Pacific Ocean.

➡️According to the above, flights over these areas are also prohibited as there is a possibility of accidents if the planes divert and go into these areas.
