Hi Phil,
In response to your questions:
A20-652 is still airworthy as far as I know. Doesn’t seem to have done too much flying over the last few years and there have certainly been a few issues arise along the way, but I haven’t heard about her being grounded.
With A20-502, I’d be interested to learn if you’ve heard any rumours about it. That’s a very nice static aircraft that one. Also happens to be up here in Ballarat, which is handy.
A20-573 certainly did crash into a mountain to the north of Melbourne. I went to the crash site a couple of years ago and although there are remains still on site, there’s certainly nothing to really write home about.
The ‘lake’ Wirraway in the latest issue of Classic Wings isn’t A20-404, and although I do know the actual serial of the aircraft, it doesn’t seem to be being publicly disclosed at the moment, so I won’t reveal it at this time. Hopefully she’ll come out of the lake at some stage, but it just depends if a suitable home can be found. As for A20-404, well there are a bunch of parts from that aircraft floating around the place. Some might find their way into a restoration at some stage, but we’ll see what happens in time.
Hope this is of interest, and that you’re fighting your health issues mate.
Cheers,
Matt
