I don't understand why people do not like these places. They are glorious examples of the architecture of that era, much like the wedding-cake homes of the Victorian era or the fake-Italian-garden homes of today.

A great example of the architecture of times back when the terminal here was considered futuristic. No way they would build it in that style if a new terminal were to be put in its place. Something like this might be more appropriate in today's day and age (nothing against Barajas Airport btw)-

Just an example of how times change and so does architecture. I think we need to respect what we have left out of the old modernist homes, they are slowly becoming a dying breed.
