		| Abstract: | 
		This paper summarises the first results of a detailed observational study of the physics of shocked H_2 excitation and dynamics in the Orion ``bullets'' (Tedds 1996) using the recently upgraded CGS4 near-IR spectrometer at UKIRT. It is very difficult to reconcile any steady-state molecular bow shock model with these observations. We have identified an additional uniform but collisionally broadened background component pervading the region in both Fe^+ and H_2 which is inconsistent with a fluorescent component due to the ionizing radiation of the Trapezium stars alone. |
