Donald Campbell also used an Avis Air Charter Aero Commander. But on that occasion it was in support of his water speed attempt on Lake Dumbleyung in WA. Had the honour of refuelling him at Perth Airport early in 1965.
Have a snap somewhere taken at the time. His pleasant smiling face is framed by the open side window as he is reaching up about to fire up number one. Perched up in front of him on the dash is the teddy bear that went everywhere with him. Named??? That little stuffed mascot was eventually recovered from the depths at Lake Coniston. If you've never seen the film clip of Bluebird on that last of all speed run, or listened to the voice of the pilot calmly saying (throat mike) so unflapably "I am losing it", then look it out.
