2) “The horizon always rises to the eye level of the observer as altitude is gained, so you never have to look down to see it. If Earth were in fact a globe, no matter how large, as you ascended the horizon would stay fixed and the observer / camera would have to tilt looking down further and further to see it.”

This is nonsense. It just isn’t true.

Do your own research: here is  a simple way to test this for yourself.

Find a view like this of a tall building and take picture like this:

Draw the red lines to extend the horizontal base of any high windows, bricks, slabs etc. towards the horizon.

You will find that the lines converge above the horizon, not on it.
I don't think that anyone would accept this claim if it wasn't hard to see the drop of the horizon with the naked eye. Taking a photo and checking than lines dioisproves Dubay's claim instantly.

You can see the same thing here:

More evidence against this claim:

It depends how high you go. Plenty of people have gone high enough to see it, but flat earthers evade that by claiming that  “they’re all in on the conspiracy, and their photos are fakes”.

### As Daimonie shows:

 How to calculate the distance to the Horizon given your height.

“The horizon always rises? No, it doesn't. What do you think the horizon is, some mythical creature? Let's show what it is. Suppose for a moment that you're shining a laser while standing on a huge sphere. You start by pointing it upward, then move it downward towards your feet. The Horizon will be that point where the laser first hits the sphere. Yes, again, it is that simple. A slightly more complicated story allows us to calculate. I took it off Wikipedia/Horizon, and it includes the calculation.”
