Reported Sighting

I can't remeber the exact date but it was 1973 and I saw the "spaceship" which was circular in the presence of two other professional people who also "witnessed" it. The intersting thing was how firstly it had white lights that were revolving and it flew very fast towards the horizon, when it went down over the Horizon a Commercial plane came into view with the typical red and green lights and was much smaller and much slower. It was in Darwinand I saw it above the old Darwin Hospital site. Darwin is the capital of the Northern Territory of Australia. Around the Darwin area there are Wandjina paintings in the rocks that are thousand of years old and look like spacemen. They have big eyes like the descriptions of the abductors.
