It has been proposed that Valentich staged his own disappearance: even taking into account a trip of between 30 and 45 minutes to Cape Otway, the single-engine Cessna 182 still had enough fuel to fly 800 kilometres; despite ideal conditions, at no time was the aircraft plotted on radar, casting doubts as to whether it was ever near Cape Otway; and Melbourne Police received reports of a light aircraft making a mysterious landing not far from Cape Otway at the same time as Valentich's disappearance.
