I've just noticed in a photo on 'airliners.net' that two RAN Squirrels performing at the VP Day celebrations in Canberra on 14th and 15th August had decals of Cookie Monster and Barney applied to the engine covers just below the rotor head.
That's cool. It reminds me of the RAF AEW Shackletons each of which was named after a character from 'Magic roundabout' (70's/80's British claymation/puppet kids TV show. Remember watching it when very young, stuffed if I know what it was about!).
When the RAAF disposed of the Falcon 900s some Simpsons characters were painted on the sides of the aircraft by HDH personnel prior to their departure (after RAAF markings had been removed). There distination was of course...... Springfield IL!
