Let us not kid ourselves that the defining ethos of display teams is always professionalism.
Anyone who has listened to the, frankly, appalling RT of teams such as the Reds knows that at times, it's all about them. Their RT discipline has nothing to do with professionalism and is instead all about "the team" - there can be no other excuse for it. If they could display their, quite frankly astounding flying skills while displaying the professionalism of the average front line pilot then I would take my hat off to them.
If they would not check in for a front line 4 ship using their comedy RT then why do they think it is acceptable for the RAF's highest profile unit?
