FH1100,
you hit it right on the head. This accident may be second cousin to the type that used to plague EMS, where the pilot wraps himself so much in the excitement and drama of the moment ("Dying child needs rescue!" looks a lot like "Fleeing Criminal grabs hostage!")
I lost 2 good friends in Vietnam when they became so fixated on the bad guys running around below them that they just pulled out way too low.
