Sharks
The 2* Grim Reaper took them after our '92 season in payment for someone's brass hat. On paper it saved 450 display hours (that's a saving of a whole aircraftsworth Admiral).
In reality we saved nothing; the display hours continued to be flown the following years, as two pairs and two solos, occasionally displaying at the same venues at the same time but making sure they didn't call themselves 'The SHARKS'.
When the Admiral asked why the SHARKS logo was still on the tail the following year he was advised that the Sqn couldn't afford to paint them out - he seemed happy with that.
The final justice? The 2* himself was taken by the light blue Grim Reaper last year.
The moral? 'The SHARKS' were the essence of the FAA, if you want to re-invent the FAA, you might start by re-inventing 'The SHARKS', not the 2*.
