Imperial War Museum, Duxford, Cambs Free to pre-booked children, teachers and helpers. Extra flights (eg for parents/siblings?) £20.
Wed 13/7 and Thu 14/7 - I don't know where or how these things are publicised, but if any of you have SN children at school in the vicinity (am assuming that long trips would be problematic for some) it might be worth mentioning to staff?
