Hover,
Try and think out of the box!!
Its not just about flying around the restricted area, it could be bringing in the corporate guests who sponsor the sport and who would be unhappy if they can't even get to the staging area.
Or going for spares or picking up technicians...............or flying in the TRA, the weather closes in and then climbing up and recovering to Cardiff or Swansea.
MS.
What is the height limit on the TRA? Nothing to stop you watching from above if it is a nice day.
