No excuse needed for this shot. Taken at the RAAF Museum's Pageant on 23 February, 2008, it shows three W.W.II allied fighters wearing historically appropriate shark mouth schemes.
From the nearest: The RAAF Museum's CAC Mustang A68-170, Alan Arthur's Curtiss P-40N-1 Kittyhawk NZ3125, and the Temora Aviation Museum's Supermarine Spitfire Mk.VIII A58-750. (Also present are a NAA T-28 and Mustang VH-BOB.)
The RAAF Museum's scheme is an Occupation of Japan scheme, of 77 Squadron RAAF, Al Arthur's an Italy Campaign 112 Squadron RAF version, and the Temora Spitfire in the colours of Bobby Gibbes' 'Grey Nurse' 457 Squadron RAAF.
Later that day the three aircraft flew a unique shark mouth flight scheme. A challenge for our readers; does anyone know of any other occasion three different types of shark mouth painted W.W.II era warbirds flew together? It's possible, but I can't recall another occasion.
