The first time I saw a UFO was in 1979 from Orari near Geraldine in the South Island of New Zealand. It was flying horizontally in the direction of the foot hills. It was one of the tradionally shapped craft
It looked like this.
I was only about 9 years old but the image has stuck with me all my life. I don't know how I knew it was a flying saucer as I had never seen them before.
I saw two a couple of weeks ago that were "growing" chem trails. these were more like orb shaped. I was going to get my camera but then the cat threw up and I had to clean it up when I cam back they had gone. Before christmas on boxing day I saw one that looked like a tiny star ship enterpise. i.e. it had the flat disk on top with a payload dragged behind. I tried to take a picture with my cell phone but as I was driving by time I got myself organised it had gone.
Anyway, I know what I saw and they wern't aircraft or weather baloons or swamp gas.
