"EMS Helo Pilot" I loved the 16 years I spent HEMSing  

Not every base, every flight or every crew. HEMS crews were much more positive- except when I got'em up at 0200 for a long haul. Overall a positive experience for an old guy tired of living out of a bag. 

NVGs made nights better than day flights.

HEMS doesn't fly a lot, my only complaint. 150 hours a year was the average last time I looked, 10 years ago.

Do not socialize with the med crew. Civil, professional exchange of information, just as you would any passenger.
