Doesn’t the Pilot have the final say on whether everything is in order? I hope RAF and ex RAF Pilots have the knowledge and experience to ensure that everything is in order.
When they turn up in the morning, whether at the location of the display or not, they will go through all the required paperwork. Their own paperwork and licenses will be checked as well?
But, the final say would be the Pilot? Or does a nice big paycheque somehow speed things along?
