Hello again... I'd like to pull out some more things that are undeniable.
I am sure that there will be people that do deny your information.
I will probably be one of them.

This youtube video shows the launch of a shuttle orbiter:
The video is on one of the rockets, so it detaches, and if you pause the video at 2:19 you can see the curvature of the earth clearly... This couldn't have been blue-screened, it couldn't have been made on a computer program, because we have videos from earth of this launch. I also saw a video of the launch of Space Shuttle Endeavor (I think it was that one) on TV, and have taped it on VHS. It shows the curvature of the earth.
It was hard to make out the curvature in the video that you chose, but I agree that it is there for a couple of seconds. Why would this video be any more acceptable to people that deny the possibility of sustained space flight than video shot from the flight deck of the shuttle in orbit?
This was public broadcasting TV. You expect public broadcasting to be in on the conspiracy?
The stock reply is "it was probably produced days before the launch and broadcast on the correct day to support the illusion of a shuttle launch."
Also, I'd like to pull out those damning calculations again about the position of the sun in the sky...
...Now, we divide that out and get the ratio as 3000^2/12806^2. Punch this into your Microsoft calculator, and you get the relative luminosity of .05, or 5%. Now tell me, when I'm in that clear field, looking 13.5 degrees into the sky, why don't I see a sun that's 5% the luminosity? This would outshine all the stars, and create a new moon-looking object.
Lots of fancy math, but since the flat Earth theory states that perspective and refraction create the illusion that the Sun sets and rises, your "moonlike" Sun won't have a chance to be visible across the pole.
[/quote]There is one way I resolved this problem: by making the earth a cone instead of a circle! Wow! Take a breather, you can live another day against the scientific community! But wait! That worn out turtle pushing the earth up 9.8 m/s^2 will make gravity be stronger as you get further away from the north pole, and a river flowing north would be plain nonsense (forget the Nile!)[/quote]
Well, since you freely admit that your model can't support observed data (i.e. Nile river), I am going to say that your model fails.
If you can't accept this argument, then you must reject all notions of geometry, which can be easily proven by a piece of paper and a high-school education.
Which part, the fact that I can't see the Sun to the north across the pole or the fact that the true shape of the Earth is a cone? That is to bad that I have to reject all notions of geometry because of this. I was sort of partial to trigonometry.
Also, you have yet to explain Foucault's pendulum.
The anomalies from the small test subject of solar eclipses shrinks in comparison with the evidence I saw right in front of my eyes (at Chicago's Museum of Science and Industry) that can only be fully explained by the rotation of a spherical object.
They have. Their explanation is that some effect from celestial motion causes the pendulum to move. It is the same effect that causes Coriolis Acceleration in the flat Earth model.
By the way, ever heard of the D-Layer in the atmosphere that varies with day and night, making ham radio communication possible? http://dzabcik.home.texas.net/propagation.html
Well actually, it is primarily the F-Layers. HAM radio communication (and other uses) is possible on other frequencies (VHF or HF) at other times of the day and also at night.
Since the shortest way to a place across the earth to send radio signals is naturally over the north pole in the FET, people will aim their radios (which send straight signals) to the north pole with no avail. That is because the north pole is always close enough to daytime to destroy that layer of the atmosphere. Needless to say, you don't point your antenna to the north pole... That's just ridiculous. You point it in the direction of the shortest path to somewhere on a spherical globe. Try this out, go buy a 400$ shortwave radio and disillusion yourself. Please.
I regularly use MF/HF radios as a part of my job, so I have done this. The layers that are most important to radio communications are the F-Layers (F1 and F2). The frequency that is best reflected by the F-Layers vary over the course of the day. During the day, the frequencies are in the 10-15 MHz range, but drop to around 3 MHz at night. The combination of the height of the layer and the "opaqueness" of the layer is what determines the possible range of communication.
How are those for responses? Hopefully you got the answers that you were looking for.
