A new inland corridor, running from Liaoning in the north to Guizhou in the south, through cities such as Wuhan and Changsha, is booming.An active interface between medical science and aeronautical technology: the physiological investigations for the XC-35.
Although the advantages of flight at high altitude were early recognized, so also were the physiological problems standing in the way of its realization. The idea of surmounting such problems by means of a pressurized cabin was advocated as early as 1909, while the first attempt to translate the concept into actuality occurred in 1921. Neither it nor several successive attempts enjoyed any real success until a project launched by the U. S. Air Corps in 1935 produced a breakthrough aircraft designated the XC-35. The major reason for the favorable termination of that venture was the thoroughness of the engineering involved. But it is equally notable that this was the first instance in the
