Totally unscientific statistic
Reading this thread made me think… and count… and then get one of these sick feelings that are sometimes referred to as an epiphany.
I’ve been in the helicopter industry less than ten years, never flew EMS myself.
Of the dozens of pilots I’ve worked with (between 50 and 100) I can only recall 6 who worked EMS for at least some time.
Of those six, two (33%) were killed in night CFIT accidents while on EMS flights. One in bad weather (fog), the other on a clear but dark night over featureless terrain.
Of the other four, two told me stories of losing (and regaining) control of their basic night VFR equipped aircraft on dark nights over uninhabited terrain that made me want to puke.
The other two only flew IFR and autopilot equipped multis.
