A Disk/cigar shaped object ,100m in lenght , bright orange to silver in colour, splits into 2 craft then reforms as one.We had been having some spectacular sunsets leading up to my recent sighting. This is my sixth to date. I was watching the sun set at 5pm. It had just set below the horizon and the sky was another painted masterpiece! Looking west from my house I can see the golf course and Airport on the hill. I suddenly noticed what I though at first was a meteor just right of the airport about 500m. It looked like a fireball. This object was hovering at tree level. When I realised that this was no meteor I grabbed my binoculars for a better look. Apon viewing the craft I was literally numb with shock. Then an amazing adrenalin rush took over. The craft was huge. I estimate about 80/100m in length. It was shaped like a saucer but more cigar shaped. It was fluctuating between a whitish silver and the most amazing intense orange. Almost like a colour that I have never seen before (if that makes sense). It also had this strange shimmering effect, abit like heatwaves on the road. This part is hard to explain...... The craft appeared to be surrounded by what looked like a cloud. The only way to explain it is to say, to me, it was a hole or a tear in space-time-reality and this object had sorta popped in for a look! I found this really hard to comprehend. I winessed something they don't teach us in science. The object suddenly began to move very slowly to the north still above tree level. About 10 minutes into the sighting the craft split into 2 objects. The both remained side by side for about 30 seconds and then joined as one again. I witnessed to object for about 15-20 minutes all up before it drifted behind a mountain and I lost sight of it. During the sighting I called a friend who has a video camera. Unfortunately due to the geography he couldn't see the craft. I have spoken to several people including a helicopter pilot who was working at the airport that day, but no one saw it. During the sighting I also observed 2 small aircraft fly near the object and land at the airport. I also got this sensation that it was showing itself to me, and me only!
