Abstract: The Orion region contains the nearest sites of low- and high-mass star formation.  Forming stars produce time-variable jets, winds, and outflows and in some cases, explosions which inject energy and momentum directly into molecular clouds.  Outflows provide evidence for accretion bursts, N-body interactions, and in some cases protostellar mergers.  I will review the remarkable explosion that occurred in Orion OMC1 behind the Orion Nebula ~550 years ago (that's when the light would have reached Earth). This event was likely powered by an N-body interaction that resulted in a stellar merger and ejection of runaway stars.  Such explosions may be relatively common in dense,  massive  star-forming complexes.   Feedback and N-body dynamics are crucial ingredients in establishing stellar masses and the IMF.
