I didn't think that the Mirage was a GA aircraft, even though they liked being down at GA altitudes!!!!!
Mirage flight manual states:
Engine failure below 10,000ft - EJECT.
Engine failure above 10,000ft - open panel next to left knee, take out brick, throw it out of cockpit, fly formation on it for best glide angle.
"No Mirage has ever landed/crashed at Laverton Victoria. A wheels up at Tullamarine and flame out with an ejection at Avalon but the only operation of a Mirage at Laverton was a takeoff."
I am pretty sure that a very senior current serving ex knuck test pilot landed the static display Mirage at Laverton prior to the 1978 airshow.
Definitely min fuel departure for Avalon on Monday though, pity that the ASI, etc,wasn't working properly due to chewing gum on one of the static ports.
And although Svenson survived his supersonic ejection, he was killed while riding his pushbike in the UK a few years later.
It's a pity that we can't ask MICE about it anymore, because he would know.
