There is a Mirage III C on the Swiss Civil Register, but this is a quite different beast to the Australian III O I really doubt the central "avionics" would ever allow the beast to fly again, the Sperry Twin gyro platform we were forced to use is steam driven technology and never did quite integrate to the BEZU attitude system.
The auto command flight control system requires quite sopecialised "Analogue" knowledge and the general electrics on the beast are a French technological marvel, when they all work.
Navigation by the Canadian CDC box is at best guess work and without radar vectoring the aircraft is unlikely to find its way home !!! no reflection on pilot skills, just a statement of fact. This is quite a different beastie from the Sabre which is a gentlemans aircraft.
A Mirage III O VFR is a frightening thought.
