Selected as a \"PI\" instrument for the airborne Stratospheric Observatory for Infrared Astronomy (SOFIA), SAFIRE will apply two-dimensional pop-up bolometer arrays to provide background-limited imaging spectrometry. Superconducting transition edge bolometers and SQUID multiplexers are being developed for these detectors. SAFIRE is expected to be a \"First Light\" instrument, useable during the initial SOFIA operations. Although a PI instrument rather than a \"Fa","authors_text":"D.A. Neufeld, D.J. Benford, E.
