I was watching television at 01:30 when I heard a loud boom sound.The power then blacked out.I thought that the cut off switch had went off again so I walked outside to my power box.I walked to the front lawn and to the east side of my house where the power box was.I checked it but it was fine.There was no sighn that anything had happened To cause the boom.But then as I turned right to go back in side I seen a large bright white circlier object coming from the direction of the sea,east.I watched it as it moved closer slowly in a strait line and as it got closer I realised it was three objects.I turned as they came closer when I got to the point of facing south they stoped.They stayed there motionless for about 15 seconds then they moved very quickly in a zig zag movement to the west.After about 10 seconds they were out of sight leaving once again with the loud boom.The next day I asked other residents if they had seen or heard anything strange,some of them explained to me a similer experiance to my own.There were three objects.At first they seemed to be one till I got a closer look.They were bright white,no other colour or changes.Each object would have been at least 100 feet from the ground.My guess is around 25 feet in diametre.A loud boom which I belied they emited happened a short time before I noticed them.They moved in a perfect strait formation from the east for around 2 and a half minutes,stoped completly as I faced south for 15 seconds then moved extreamly fast in a zig zag formation to the east.I witnesed this for at least 10 before they completly disapeared.I am a Diversional therapist and a redident of the suburb of Annandale estate,Townsville for Three years.One other witness who I know as a friend is and ex soldier for the Australian Army and also a computer expert.Other Witnesses who I do not know personly are Full time Military personal at the Lavarac Barracs in Townsville.
