FWIW, I have often seen CASA exemptions for a number of Police Air Wings around Australia that permit flying at night without the lights on.
Thanks for that. A completely dark chopper is frequently spotted flying at a fairly low altitude over Surfers Paradise without even a red beacon. I assumed it was the cops, but it's good to know for sure.
I don't know who they think they're kidding because with the echoes off the high rise buildings it makes more noise than the space shuttle, so it's hardly covert.
