The windmills were few and far between on my travels in the oil game but most were busted up so your on to something there Kaz
Always wondered why most of the blades were twisted up on them
Remember one day a J230 flew in to Innamincka from Birdsville on a hot stinking day with the thermals popping, the boys said they got to 7500ft and were still in them so just gave up and hung on
On the ground they were ready to head to the pub and I asked them if they were going to tie it down, they asked what for, I then pointed out to them the 15 or so dust devils popping at that time within 5nm from the strip and some of them were quite huge
Tie downs came out with a few extras quite promptly amongst the sweat, flys and grumbles from the lads trying to screw them into the baked earth of Innamincka
