A brilliant light moved super fast in the sky and zig zagged away at unearthly speed.

On the way home but before opening the garden gate I stopped and looked up to enjoy the clear night sky. There was a brilliant 'star' like light that moved like a super fast airplane going from right to left. I watched it. All of a sudden it zig zagged and shot off to the right at incredible speed and disappeared.
When I went inside and told my husband I thought I saw a UFO, he said that people saw those strange lights that were considered UFOs all the time in the night sky in Calcutta, where he lived.
