This is a question that has always been on my mind. Why build airports in challenging areas such as in between mountains or close to buildings? Could it be that there was no where else to build, or it was cheaper to build? And when I refer to "challenging" it's for example the old Hkg airport, Inn,Gua,Tgu,Sxm, etc.
