But at others, as the hollow sounding wind swept by us, it seemed to clear the air space
around us so that we could see afar off.
TAV said air spaces of many European countries were currently closed, adding some states, including Germany, were getting prepared to open their air spaces to traffic soon.
Pointing to a recent statement by the General Directorate of State Airports Authority of Turkey (DHMI), TAV said there was no necessity to close down the Turkish air space at the moment.
But what's emerged is that these air spaces have certain properties and functions," said Witmer, Chang Professor of Paleontology in Ohio University's College of Osteopathic Medicine.
Witmer suggests that the air spaces helped lighten the load of the head, making it about 18 percent lighter than it would have been without all the air.
Overall, the amount of air space was much greater than the brain cavity.
