Balloon observations of interstellar CII (158 microns) and OI (63 microns) forbidden linesInterstellar CII and OI forbidden lines were observed by the Balloon-Borne Infrared Telescope (BIRT) with a Fabry-Perot spectrometer. Two balloon flights were successfully made. With a method of 'frequency switching', diffuse CII forbidden-line emission was efficiently detected and mapped in extended regions around HII/molecular cloud complexes and in a wide area of the Galactic plane. It has been shown that the CII forbidden-line emission is very strong and ubiquitously distributed in interstellar space in the Galaxy.
