I am often amazed by the way in which pilots are sometimes around offering things like Young Eagles flights (USA flight experience flights to children) or trips to their friends' offspring when they haver, maybe, a hundred hours.
I am a low time pilot, 100 approx. hours years ago and another coming up 100 recently but I would not dream of doing Young Eagles and, in fact, I limit my own children's exposure, partly caution and partly because I fly an amphibian and they have a particularly poor record locally.
On one hand I recognise that a PPL is properly qualified to fly passengers, family and friends and there should be no reason he may not. On the other hand I can see the frailty of my skill and experience.
When I worry about my own kids how could I risk other people's?
(I am not commenting on any particular offer by any particular pilot and I know perfectly well that many 50 hr pilots are more careful and respectful of the risk than cavalier high time chaps.)
