Hi y'awll...
The whole interesting video of they way they performed this was either on the SBS or ABC a few months ago.
Lots of time required to process all the info they gathered.
They had one or two small glitches along the way.
One of their processing computers was over heating...so they left/chocked the door open to improve the air flow.
Then, the weather didn't co-operate in one area, so there was a big decision as to go ahead with the operation or not.
Decided to go ahead & hope for the best.
Turned out rather good.
I'm fairly sure it was on the SBS, but cannot find the program.

ps. I did record it on my PVR but did not keep the program.
pps. I called the SBS TV/Radio number & the lovely lady took a lot of time, looking up the info on the program.
She had a little trouble finding it but finally came back with the info.
She verified that it had indeed neen recently (A few months ago), screened but could not say if they would re-screen it.
Pity, as it went through the whole process of gathering all the info & set up procedures they had to go through.
