Lake Eyre advice needed

One thing I feel is a must do for me this year, is to see Lake Eyre in flood from the air. I have been researching this, & Flights go from William Creek SA appear to be the go. I can get a flight from Brisbane, but Expensive for a day trip, but good for time poor, maybe not enough time in the air over the lake, worries me.

I was wondering has anyone done this & could help with this trip. I would prefer the William Creek trip, the drive in the motorhome would be an adventure, as I only use it for week-end breaks at this stage, Just got to talk boss into giving me time off. Thanks Wayne
