Hang on a sec & I'll fix that up for you.

I may be wrong but i think I read the space x people stating the second stage didnt separate as planned but didnt effect mission?
I read that as well. But they seem to ignore that for some reason.
In regards to the alleged "radar" screens, they looked way to fake! Anyone who has ever seen a "media" used doppler radar could tell that is not conclusive evidence that should have even been posted!
As for the video? It would be easy to cast aside any suggestions that this is a ufo or anything else questionable had only one person caught tape of it. However, there are quite a few people whom have witnessed it, let alone got video....so I would have to say its interesting to say the least, but UFO unlikely. Probably meteor, or like someone above said, military testing. I know here in the US, our media always ignores or states debris from space or some oxy moron comment

There is a lot of poor information being spread on this thread, so as an aerospace engineer I thought I'd put my ideas down in simple terms so that you can see that the Falcon 9 explanation is possible.
1. Falcon 9 is a 2-stage rocket that uses liquid oxygen and rocket grade kerosene (RP-1). Stage 1 sits at the bottom, then stage 2 above it and the payload on top.
2. Falcon 9 lifted off from Cape Canaveral, Florida on 4th June at 2:45pm EDT (or 1845 GMT). This is 4:45 am on 5th June (local time) on the east coast of Australia.
3. The rocket lifts off heading east and stage 1 burns for about 3 minutes.
4. Once stage 1 is empty, it is jettisoned and falls back down into the Atlantic Ocean (east of Florida).
5. Stage 2 then ignites and burns for just under 6 minutes.
6. Once stage 2 burn is complete, the vehicle is in orbit at an altitude of about 250 km (150-170 miles). It is orbiting around the earth in an east to west direction (at about 28,000 km/hr or 17,400 miles/hr).
7. Normally, stage 2 would be jettisoned once the burn was complete and it would either remain in orbit or another burn would be made to "de-orbit" the stage where it would burn up on re-entry.
8. However, it is understood that the stage 2 was left attached to the payload on this mission.
9. This orbit is an ellipse where the altitude above earth varies from 230 to 270 km. The orbit will trace a curved path on the earth's surface that will take into the northern hemisphere and down into the southern hemisphere.
10. The orbit will take it east over Africa/Europe, then Asia/Australia and then back over the US. The time to do one orbit (once in orbit) is 89 minutes.
11. If you look at distances from East Coast of US to East Coast of Australia, you will be looking at approximately 60 to 65 minutes (2/3 of orbital distance).
12. Therefore if you add 65 minutes to 1845 GMT you get 1950 GMT or 5:50am local time on the ast coast of Australia. So the timing is right.
13. As for the spiral, this is possible if stage 2 is spinning and propellant is leaking or being released.
14. The video of launch showed that the rocket was going into a slow roll during ascent. If this was not corrected, the roll would continue while it was in orbit. It's in a vacuum so nothing to slow or stop the roll.
The only bits of information that are missing is the actual (official) orbital track that shows the path over the earth during the first orbit and the mission log showing whether anything happened at 1950 GMT. This is only something that SpaceX (or NASA ) can provide.
So all we can do is wait for SpaceX to make an announcement and either confirm or deny that their rocket was responsible.

I humbly apologise for coming in late, and not reading all of the thread.. but I didn't see a direct link to this in the last few pages, namely a map of the track of Falcon 9...
Not my image - and I haven't verified the orbital elements for myself, so I won't absolutely guarantee that path, but I think the numbers are out there -just bein' lazy...
Again, I apologise if that has already been posted.

Not sure that this thing is/was, but I'm fascinated. If its a genuine unknown then the story will go global eventually.
