Ans.In short we can say it is very cold,the air in the mesosphere is very thin and it is the highest layer and very far away from our planet hence it is very difficult to survive in this layer. We conclude that planes cannot fly in the mesosphere. Note: Remember also the plane can't fly in the thermosphere.
Most meteors vaporize in the mesosphere. Some material from meteors lingers in the mesosphere, causing this layer to have a relatively high concentration of iron and other metal atoms.
