  The Next Generation Balloon-Borne Large Aperture Submillimeter Telescope
(BLAST-TNG) was a unique instrument for characterizing the polarized
submillimeter sky at high-angular resolution. BLAST-TNG flew from the Long
Duration Balloon Facility in Antarctica in January 2020. Despite the short
flight duration, the instrument worked very well and is providing significant
information about each subsystem that will be invaluable for future balloon
missions. In this contribution, we discuss the performance of telescope and
gondola.
