Driving I saw something in the sky, I looked up abit, then it sort of flashed away, and was gone.

My mother was teaching me to drive on the country roads surronding the town which i was living in (Casterton). I was driving allong, when i noticed something in the sky. There wen't many clouds around and this looked like a funny shaped cloud. I know this sounds unconvincing but it had the shape of the Enterprise, from star trek. I thought what could that be. I was staring at it trying to figure out what it was, it wasnt dark, it was getting near twilight. Then all of a sudden it kind of flashed off and was gone. I yelled at my mum and sister to see if they saw it, but they were too busy looking at the country side
