A Michelson interferometer has been built and flown successfully on a 60-cm-aperture balloon-borne telescope for astronomical spectroscopy at 0.05/cm resolution between 100/cm and 250/cm. The telescope and interferometer are described, and spectra of the H II region M 17, showing emission lines of forbidden O III at 113/cm and 193/cm, are presented to illustrate the flight performance. An average rms pointing stability of 4 arcsec was achieved with the telescope, and the flux sensitivity reached was within a factor of 2 of that expected.
