Just to put your minds at rest, going in to the RAF at a young age is not like 'Get some in' (tv programme). The boys are well cared for, if they have problems there is a Welfare Officer they can go to who will give them all the advice they need. They will not be allowed to get themselves in to any bother. Your son is very lucky, he will have his own room and not have to sleep in a barracks where they used to sleep 12 at once. His meals will be very well cooked and they will also teach them to be independent, showing them how to clean and iron their clothes for example. He will love it. The RAF is not like the Army either, they are not half as strict. Good luck to him, I hope he has a wonderful time, and see a lot of interesting places, although there are not so many overseas postings these days. He will make lots of friends and some will last a lifetime.
