I was standing on my front verandah having a coffee & cigarette at 11:55am local Queensland time on Saturday the 2 of Feb 2013 on Russell Island looking east towards North Stradbroke Island I was thinking what a beautiful day it was after some very heavy weather when I noticed a white 'craft' moving very slowly in a south - north direction. It just appeared. I observed it for about 6 seconds, flying dead straight, when it just winked out. I thought 'What the hell?' It was flying against a very clear blue sky, with white clouds way above it so I know it didn't just fly into clouds and disappear. I watched the same patch of sky for another 5 to 10 minutes when it re-appeared. This time it was above the flight path it had taken and further south but still flying at the same speed and in the same direction, again for about 6 seconds, but just before it winked out it seemed to 'bank' in a left direction. It appeared slightly larger. Then once again it simply disappeared against a very blue sky. Then about 10 minutes later a helicopter appeared flying from the general area of the craft over North Stradbroke Island from east to west straight over my house. I stood on the verandah for another half hour but observed nothing else. I first noticed it because it seemed to just appear out of thin air. I was looking at the right spot at the right time. Pure chance. When I first noticed it I thought it was an airplane. Even though it had been clear sky I thought it might have come down through the clouds but when it just suddenly disappeared twice I knew it was not 'normal.' Was it a UFO? Yes. Was it a man made UFO, perhaps.
