Sorry ... no rego yet. The plane was down from Mackay and the 4 gents were down to have a look around Blackall as 2 of them had apparently grown up in the area.
I've since found out that one of the gents is in Brisbane with suspected spinal injuries. I'm gonna see if my RFDS Doc mate, who is also a CPL, was on duty yesterday and can fill in any details. It's highly likely he was called to the scene.
