EMS accidents
As we all know, the trouble is that two of the three examples cited were not strictly "EMS" accidents. The two helicopter crashes were at night: one in bad weather; the other at very low altitude. Neither ship had patients onboard. Either accident could have happened to any operator that flies at night. It would be wrong to single out EMS for these two. But they will. Perhaps the NTSB ought to widen their focus a bit and do a safety check of the entire helicopter industry.
