That is the full unadulterated .pdf at that .mil URL in that image up there, converted automatically to .txt

the block of data in question is here:

Where does this say there is a five mile ice wall circle around the entire earth like some kinda cosmic Trump finally protected us from the illegal aliens?

It is talking about the *possibilty* of optical illusions

At least you believe it's a mirage at 60,000 feet in the air

You could believe that

Please go there, and realize you are not likely to see this anyway

I dont

Please, bear with me here a moment

Why just that one spot?

Your 5 mile high ice wall would be VERY long, yes?

not just when approaching what "The Man" calls the polar region?

It's informing the navigator that distances can seem to be different depending on weather and atmospheric conditions

You jump to it saying, "Hey, this is the excuse why every time you are 300 miles away from here you will see ice"

When it's only a word of warning about a potential event

Like I said you could choose to believe it's a perfect mirage floating 60,000 feet in the air. I don't.

look at this mirage

and this one

this is the sort of phenomena they are talking about

what perfect mirage?

your perfect mirage is a confirmation bias, an idea you have made up for yourself based on bad data

please show me a picture of the perfect mirage, from, like, an .edu .gov or .mil site

and not a zany YouTube vid?

You are taking text that is warning navigators about phenomena that can make them misjudge distances, and reading far more into it than is actually in the text.

Go there, see it for yourself, take a picture, get back to me

cheaper than a caribbean cruise probably

It is warning of a potential event, you are very unlikely to see it like that, mirages are heavily dependent on multiple factors

You think you could see a mirage from 300 miles away over a curve. I get your point.

And this is your 5 mile high ice wall right? https://media.discordapp.net/attachments/489627090300305418/566331752692449300/FlatEarthMemeFail-DistanceToAntarcticMountains.jpg

No, I think mirages in the area could convince a navigator they saw a mountain that is actually 300 miles away, because the navigator did not see the mountain, but instead a mirage that upon visual inspection resembles that particular mountain, but since he's in the right area for those sorts of mirages to be possible, he could actually be so far away from the real mountain that it can not be spotted. Since the entire block is about mirages.

This is a fake iceberg, it just isn't real, it isn't real anywhere

Could you explain this one?

So this text to educate and warn navigators is saying that in the past seasoned navigators thought they spotted the mountain they were expecting, but was actually 300 miles away from where they thought they were, do you understand?

Ah, now this one is easy, the village shaman blessed the kayak, and everyone knows that bird bones have helium cores.
