did they block a window on the top of side. Can't figure out what it is.

why couldn't they make the seats wider and reduce the unnecessarily wide passage!

Well Bizzy, it does have 2 fans but that's it. Maybe the weather in the winter months, when the commercial service runs, does not pose much problems regarding ventilation.

A great view all right, but the persons sitting there will suffocate!!! No ventilation, no AC, nothing?
