Maybe not quite what the original poster meant but perhaps worth discussion.
I have been flying a a while now and in latter years, have thought long and hard about flying with either my children or someone elses.
Whilst we would like to think that we take great care and that our form of sport is very safe, I believe that I take a calulated risk every time I fly in a private aircraft. As an adult I have the opportunity and capability to weigh that risk, a child does not.
My personal decision is not to take children flying.
