Considering how in our modern day and age, seeing (and hearing) airplanes regularly cross Nashville's skies does not appear to make us think twice, doesn't it make you wonder what life must have been like when the first forms of flight were being tested? I suppose to us, it would literally be like seeing pigs fly. Almost. Well Metro Archives is attempting to answer that question. Starting March 28th and running through May 31st, there will an exhibit in Metro Archives highlighting the advancement of aviation technology as Nashville experienced it.
