It is odd to have this category in the aero database.  It appears that the one invention in this class, which appears to be a balloon on a tramway driven by a fan, could have been applied to mechanically deliver food or water or something to livestock through the air.  Thus this aero invention would have an ''application'' in the agricultural industry. Using modern classification methods the invention would not be classified into the industry of application by its technological innovation -- an aero one.
