unusual lights above air port and cityWhilst driving south past airport approx 10 km north of Mount Gambier, South Australia I saw three white lights elevation approx 30 degrees on west side of air strip and thinking it was a plane about to land watched out of interest however whilst it was lined up on an approach past it had three white lights in a line but no nagigation lights. The airport landing lights were off when they should be switched on by the pilot when landing. There was no noise and after a few seconds i realised after alighting from my car that the lights were stationary in the sky. I could not see any shape at all. I continued on after about a minute and while entereing the city saw an orange glow at about 45 degrees elevation traverse from s/w to n.e towards the airport about 10 km away. it moved quite slowly but in a straight line not deviating and had no navigation lights or sound at all. It had a haze around it however and was not man made.
