They do them from Barton aerodrome.
I don't have a number as someone else organised it, but I can get hold of it for you.
It cost £150 for a sixteen mile flight, for 3 people. Kids cost same as adults.
Would imagine if less people go it could cost more per person.
It's the same as with the ballooning, they let you know the night before if you are likely to be flying.
A few piccies here we took when we went.
