I know that there are those here that will most definitely call me a nut, but I know what I saw.
20 mins ago I was outside watering my lawn, absolutely clear blue sky not a cloud to be seen. As I do, I just looked up and saw a nice con trail moving west to east and going at a fair clip, so I thought, yep he is in the Jetstream. As I was watching, I saw an object appear to the east of the jet, what peaked my interest was that it was not aircraft shaped and was not producing any con trail. I thought maybe a weather balloon, but it was visually moving very fast in the opposite direction to the jet, and I thought, I hope they are separated. This object went past and above the jet and changed direction to cross the contrail. It disappeared whilst crossing the contrail and re-appeared then changed direction again following the track of the jet, it then circled the jet an as suddenly as it appeared, it disappeared. I though I was seeing things, maybe a floater in my eye, but this object was around the same size as the jet and appeared to be roundish in shape. This is why I originally thought of weather balloon, but balloons do not do radical changes of direction and all of a sudden disappear. I opened up Flight Radar on my phone and confirmed that the Jet was QF647 Perth to Sydney F410. Nothing else within a bulls roar showing on the app.
Ok, I have no other explanation as to what this was, but I know that I will be accused of being a lunatic, but those that know me will confirm that I am pretty straight and not open to coming up with "tall tales".
As you know I have an Aviation background and am pretty aware of what flies in our skies and what should and should not happen.
This was a definite unexplained happening.
