I agreed to take a youth flying who had a "learning difficulty" - a boy whose behaviour in the air was perfect. Only after we landed did his "carer" tell me that his difficulty was spontaneous bouts of uncontrolable rage...........and she was amazed that he hadn't thrown a wobbly in the air. What on earth made her think that he was a suitable passenger in a 2-seat aircraft???????? Next time I'll ask more questions before agreeing.
