I live appproximately 400 metres away from the Ocean, this is not the first time I have seen usual craft.A good friend and I were lesurly walking our Dogs ealier this evening (remember we are a day in front of the U.S)on the beach.The night was clear and tranquil, the ocean was active (as can be typical for winter)it is unlikely any conventional craft would be sailing these waters on a winter's night. I was the first to spot the object, it was difficult shape to configure at first, it had a dull crimson beam, there was a dinstinctive hazy mass serrounding the light, it was traveling northward at sea level. I immeadiately pointed out the obscure object to my friend. He saw it as well, we immediately realised that it traveling at an enourmous speed.Our Location distinguised how fast the object was traveling, I saw it pass the port of Outer Harbour (located 30 Km away) within 2 minutes! I made an estimate that it must of been traveling at 1200 kilometres per hour to reach outer harbour in that short period of time. The object momentarily disapeared, a military aircraft followed in persuit, but obviously lost its coordinates and flew in a circle. After five minutes the aircraft left the scene. In Adelaide we have the largest airforce base and armed forces research facility in Australia known as the "RAAF (Royal Australian Air Force) technology and defence facility located 25km north of Adelaide. So my collegue and I were very suspicious as we knew that this was more than an unusaul craft to catch the secretive atentiveness of RAAF. Coincedentaly as the RAAF servailance craft left the scene, the undentified craft reapeared and began ascend southward north of outer harbour, then it veered Southeast closer to the shore, within a minute it was within a kilometre from us, from there we were able to define the ahape of the object, it had dark tansparent haze with a cylindrical shape but rounded dimentions like a piece of m&m candy. We then noticed 2 more objects of the same nature following it further out to sea! , they t oo possesed the crude crimson lights.Within a 30 seconds these other craft disapeared. The original craft then sped southwesterly out towards the open sea, it came near the oil tankers and its lights dimmed in 20 seconds then the object vanished from our view. I have not bothered to contact the authorities as I believe they would attempt 'fog' us off with lagitimacy E.G a weather baloon or servialance aircraft.However I thought it was wise to contact your agency about such specticles.
