Flying above the earth, there are a lot of clouds (of course). However, there are a few clouds that seem thicker. Come closer to the clouds, it's obvious that they are holding something: a building, to be precise. The building is a white-walled building with a red-cross by the front door. It is obviously a hospital, miles above the earth. However, it is founded enough that it will not fall to the earth.

All are welcome, especially birds and aviators. Even if you're not a bird or aviator, the staff here knows how to help you. [If need be, the staff can always beam you down to a different hospital on the earth.]
