Eric Dubay’s claim
He points out that the author uses a flat Earth model instead of a round one.
Short fact check
The author says that the Earth is actually slightly flattened at the poles.
In other words, he knows the Earth is round.
And he explains why a flat model can still be useful.
Key pages
11 and 10
Assessment
The document doesn't prove that the Earth is flat. Quite the opposite, in fact.

Eric Dubay’s claim
Eric points out that scientists use flat Earth formulas.
Short fact check
The author is asking a very specific question.
When are flat Earth formulas good enough?
He explains that the flat and round models can give different results, even before we reach the radio horizon.

Eric Dubay’s claim
The researcher compares flat and round Earth models.
Eric points out that the results can be very similar.
Short fact check
The researcher also tests a much larger ice sheet.
And this time, the simple flat model can produce a large error.

Eric Dubay’s claim
Eric is impressed because the researchers begin with a flat Earth model
Short fact check
In fact, the paper explains that the simple flat model cannot describe normal satellite orbits without engine power.
