This presentation discusses the advantages SOFIA offers for sub-mm VLBI in atmospheric transmission windows. ALMA-SOFIA VLBI at 690 GHz opens opportunities for observing the M87 supermassive black hole photon ring and may be the only way to achieve thisin the near term. The prospects and benefits for such VLBI observations in the 690 GHz window (and345 GHz) are presented. Primary hurdles and potential pathways are briefly discussed. Further scrutiny and work to develop this concept would be useful. |
