UFO Sighting in Sydney, New South Wales on 2017-11-10 10:30:00 – I was watching planes come into land and saw 3 black ballls flying in and out of the clouds

I was north of sydney airport visiting a friend in the park when i noticed a plane coming in to land, just above the plane in a cloud i witnessed 3 black balls flying in and out of the clouds. at first i thought they must have been military planes but on closer inspection there is no way they could fly like that. the objects hide in the cloud in my photo you can see the plane on the left and the black balls were in the cloud on the right i used an iphone 7 with the zoom function.
