I was going to crunch some numbers for measuring the ISS's altitude by comparing it's actual size to it's visual size at sea level, and using that to fathom out an approximate speed(I might need help for that). Before I/others go to that kind of trouble though, I want to see if FET proponents dispute the size of the ISS.
By NASA and ISA estimates of the current hardware attached, the ISS is @ 300 feet from leftmost solar panel to rightmost solar panel (or vise-versa).

Is it anyones assertion that this size is smaller/larger, and if so by how much?
If you show balloons and imply they can be what people saw instead of satellites, you are implying that they move through the sky at the speeds people see satellites moving.
The ISS is not traveling at the speeds quoted by NASA. Since the craft is much closer to the surface of the earth it can travel much slower to pass across the sky.
On another thread I did an approximate calculation to show that the ISS was really high up and travelling very fast:
This object is clearly moving very fast, because it travels around the world in 90 minutes (visit any satellite tracking website). If we transform the ISS's orbit onto a FE map we get this:

The yellow ellipse is the ISS's orbit.
If we estimate its size, it's roughly a circle 20,000km across, which means it travels 20,000*Pi km in 90mins which gives a speed of about 40 kms/s.
We can clearly see through a telescope that the object is not aerodynamic and it is not glowing due to atmospheric friction. Therefore, it must be above the atmosphere.
They would just argue that the satellite tracking station is part of the conspiracy. I waited for and saw just the hint of the ISS on the horizon after watching a last quarter moon transit this spring, but I'm part of the conspiracy too probably, since I own a telescope...
Any orbital path converted over to FE loses hundreds or even thousands of miles off it's flight path anyway, so it's not propitious to us RET proponents to argue conversions that would throw off our real world estimates, and would just be disputed anyway. My main point for this thread was to argue flight paths, not to end up in this circular argument about the existence of satellites that we're stuck in now.
Blimps for christs sake...

And for a kind of off tangent thought, I came to this site about a month and week ago, and in some thread I read that day Tom linked to some post where he explained his curving light theory. Well either in that thread, or some thread that was linked to in that thread I came to a post where Tom, obviously in his pre-satellite denying days, had a long ass post where he explained that some satellites were skipping like stones across the atmosphere, except curved, and all the rest were big ass towers. The first person to find that thread/post gets an IOU from me for anything that you want that I can do well, within reason in my discretion...
