In reply to Beardyman:
Do what I did a few years ago. Mate of mine had a really bad fall- head injury- and the helicopter crew saved his life by getting him to Bangor.By the time I got to Bangor it was a couple of hours later.After sorting out my mate , I went and found the helicopter crew and personally thanked them. (they were waiting to fly him onto a neurological unit at Liverpool).
The pilot said I was the first person who had ever done that ( in a way I was not surprised) to him and his crew.
So go and thank them face to face.They will appreciate it.
