描述
The concept of having airfields underground has been a long considered possibility however those who promote the idea are considered to be slightly unbalanced. However when all the issues and advantages are considered then the feasibility and possibility of such facilities becomes a possible reality. The environmental benefits and new technology make the use of them a cool challenge. For many people the concept of underground airfields must seem to be totally crazy, an idea dreamed up by a mad man, but that is what they thought about men taking to the skies in flying machines.
