You're not thinking clearly young man.
First has this potential trip been Risk Assessed to the local authorties criteria? Forms filled in? Child protection register for the grown up helpers? Do first flight have national governing body qualifications? Has the governing body been notified, headteacher, Local Education Authority? Minimum six months to get approval... then you need consent letters. If this is an educational visit then the 'school' by law has to foot the bill, parents may be asked for VOLUNTARY contributions towards the cost of the trip.

(if you think that wees on your fire I'm sorry but that is the process that I have to go through every time I want to take my class of special needs kids out of the building. I kid you not! And that is the simplified version too, County have bought an all singing and dancing visits database on which we have to record trip details online aswell as fill in all the above mentioned bits of paper)
Oh man, trust an adult to put a dampner on things
