I think the display team supported by Bord Failta, would be a good way to go, with the aircraft run and 'owned' by the AIR Corp.
But we need not be talking of expensive or thirsty aircrafts here. Touch of Deja vue here, have we spoken about this before?
The old Rothmans team[victim of pc culture] used Pitts Speicals when their Stamps wore out, and were pretty exciteing, don't know what their reincarnation were/are called.
The Swiss Air Force, use PC-9's, but, to be quite blunt about it are mind-numbingly boering to watch.
This is not the fault of the aircraft, remember the 75th aniversary air show, we were boered to death by a Dutch F-16, then some looney came on with an Alpha-jet and woke everybody up.
Sorry, I'm wandering here, you might not be able to put together a display team useing reserve aircrew, summertime, they will be busy with their real job, bringing about a third of our population to hotter spots to attempt to get skin cancer and appear in dodgy Sky doucmentries.
