Nob jockey there is a wonderful podacst with a US official explaining all about the Raptors Pilot training and international flying schedule. He explains how the F22 has been offered to cananda, australia and GB for public displays as we are such staunch allies. Offered, not begged arranged, cajoled or negotiated.
Business is business. Getting ac to fly at an airshow is not some top secret extra special cloak and dagger mission. It happens every day hundereds of times around the world. Its called an industry that people are paid to be in. Procedures are in place. All your hysterical mysterious meetings after long tortuous flights are a side show and have nothing to do with anything other than planning for what has already been decided.
It is very simple. We invite the yanks, they see what they can offer, that gets run past the oz govt. Subject to operations, the logistics are planned, schedules arranged, clearances given, support put in place, forward ops deployed, aircraft moved, amen. The yanks do it every day, its a nice mission for them, they love it. They would send more but they dont have much money atm.
People getting paid to organise an airshow is not hard work.
