I was in my backyard taking the dogs out to do their business. I heard the sound of a jet-aircraft approaching from behind me, above. I looked up directly above me, and saw a white reflective orb or disc type craft.it seemed to stay in place for a moment until the aircraft caught up and was ahead of the UFO. As the Aircraft moved in a West-North-West I saw more, and noticed that there was a second UFO that looked the same as the first one, tailing this craft from behind the jet aircraft, and equidistant to the other craft. The way they moved was synchronised in a way as they were both going the same way, following this craft at the same speed it seemed. They didn't make any noise, and the only noise that was being emitted was coming from the jet. I watched until I couldn't see them past the backyard trees.The whole event lasted about a minute, between 11:46 and 11:47am
