Tonight 31/12/2018 a flying object in the night sky caught my attention as it appeared first as a very bright light until it came closer and then I could see small red and white lights. I thought it was a passenger jet but it made no sound and passed from south to north of the Southern Peninsula, Cape Town. I could not distinguish a shape, but thought it was unusual as there was no sound. It was travelling at the speed of a passenger jet one can see and hear on any given day. I pointed it out to my daughter who also wondered why there was no sound!
