Most HEMS accidents occur at night. Yes, it's all about choices. When you turn down a flight for weather and then it begins to clear all the way until morning, you think "Why did I do that?" That can just as easily act in reverse, when all indications are that that the wx will improve but then goes in the hopper. But accidents happen when the best laid plans of mice and men go awry. These are the times that I'm talking about. An auto pilot turned on and ready to go on a moments notice still seems to me, the best way to improve the statistics.
