During Summertime back in my bicycle riding-newsboy days, you'd often smell them before you'd see them...
Some critter that had challenged an automobile and lost. The collision would most generally explode the animal, pushing entrails outside its body...
A buffet for the flies and maggots.
This guy's face looked like that.
Both eyes were there, but his nose, mouth, and jaw were gone.
His lower face looked like exactly like the disemboweled animals I smelled, then rode passed as a youth. First responders surmised he was drunk and passed out in the middle of the road, just over the crest of a hill. Whoever struck him may not have seen him... may not have known they'd run over a human being.
Oddly, these first responders were on their way to pick up another patient when they happened upon our patient lying in the road. They had to call out another ambulance to respond to the first call they were dispatched for...
This guy needed them much more. This guy was dying.
The landing zone was oriented in such a way that I had to land with the tail rotor facing the ambulance. Dangerous. I secured the LongRanger's flight controls and positioned myself behind the aircraft to tackle anyone who might approach the tail. That put me near the back door of the ambulance. When I was sure the dust had settled and the situation was under control I walked to the side door of the ambulance to watch my flight nurse at work. A warm night, the side door was open for cross-ventilation. As you can imagine, this guy looked ghastly. My nurse was desperately trying to insert a tube in his windpipe to establish a secure airway for him. She was struggling, sweating, frustrated. She had no landmarks to use to tell what was windpipe, what was crushed meat.
I looked at the guy's eyes...
They were pleading for help. My nurse continued frantically trying to help him.
Slowly... ever so slowly, the pleading look left his eyes and became blank. Ground EMS folks started CPR on him while my nurse continued her attempt to establish a clear airway for this poor guy.
Some flights will bother me forever.
This was one of 'em.
