??? I have seen them land on a sandbank in the Burdekin R by the light on a chemilume stick thingy.
Why would they not just turn on the lights at YLRE and land on the tarmac?
Given that you don't actually have to "land" a chopper, why would it matter if there were works in progress?
Sounds like a load of crap to me. Can't believe that the AJ wock wock boys were too anxious about anything!
