I'm due to go out on the 14th September to fly with a friend. I sent my stuff off to Oklahoma too. Spoke to the CAA today and they said they are doing nothing about it at the moment, so it looks like we will both have to hire a C152 each using a Student Pilor Cert, when in the states and not a nice PA-28 Archer II.
This really does need to be sorted out soon!
