Why is your window a globe?

[The Cadet]

Imagine a rocket going straight up. If the rocket, before going up, is "traveling" equal with the earth's rotation...how come when it goes straight up, it doesn't move diagonally?

That's a timelapse of a shuttle launch. It curves with the earth. But it would be equally possible for it to go against that curvature, because it's a powered launch and can adjust its own trajectory. But in order to observe a launch "straight up", it would also have to travel with the spinning earth. Here's a graph from NASA of the position taken by the Apollo spacecraft when it enters orbit:

So neither your observation nor your conclusion from that understanding are accurate.

Next, if the earth was a globe.....why is the horizon always at eye level? Forget the fact that the curve is 8 inches per mile squared so that 10 miles...the curvature should be thousands of feet. Yet that is not what we observe, this proves the earth is flat.

Why should there be thousands of feet of curvature? I have no idea how you got that figure, but it's pretty easy to see why the horizon would be flat if we were on a sphere. Here, try this experiment sometime. Take a sphere (like a basketball or a ball of yarn), and stick a needle in it vertically. Then, pull a string through the needle and pull it taut so it forms a tangent with the surface of the sphere. Much like so:

(The pin is the little human, the string the red line)

Then, drag that string to every point you could form that tangent to, and mark those points. What you will end up with is a circle around the outside of the ball, with none of the points higher than the others - from the line of sight of the pin, the horizon will appear flat. And that's true despite the fact that the pin has a far higher relative vantage point than you on the earth.

Better yet, watch one go up in person. They usually turn to the east as they rise.
They do this to take advantage of the earths spin of ~24,000 miles per hour that
they already had going from the ground. Like a head start.

10 miles is 66 feet of curve.

Your window pane is curved that much.
But we don't call it a globe, we call it flat.
We don't consider the 3 mile radius circle
around us to be part of a globe. We think
of it as flat as does everyone on the planet.

Examples don't prove points. The issue was draping.
Draping over a globe is as easy as a flat table.

Looks to me like there is a good bit of both of those globes that don't have any draping materials touching them. Thanks again for proving my point.
