Congratulations
EVER SEE A BULLET HIT THE WATER?
Same effect when Elon’s “Rockets to no where” hit the Dome!
Maybe PDJT will mention Lamestream or Dan will post the ice wall..
Lamestream Media always tells the truth…🤣🤣🤣🤣
Fact check: NASA says Earth is a globe, uses 'flat and non-rotating' model in equations
The claim: NASA admits the Earth is flat and non-rotating
A Dec. 5 Instagram post (direct link, archive link) shows a TikTok in which a man reads and shows screenshots from various NASA reports that reference a "flat, non-rotating earth" model.
"NASA documents admit the Earth is flat. When will people learn!?!" the caption says.
The original TikTok has been removed from the app. Various iterations of the post have spread to Facebook and Instagram.

NASA has consistently said the Earth is a round, rotating globe, and the documents referenced here don't prove otherwise. The "flat, non-rotating earth" model is a common technique used to generalize mathematic equations, experts said.
Model is used to generalize equations
The reports in the post are real and use the term "flat, non-rotating earth." They are not, however, evidence NASA believes in the flat Earth theory, said Robert Margetta, a NASA public affairs officer.
"The Earth’s rotation can be seen by the naked eye while observing sunrises, sunsets and the position of the moon in the night sky," Margetta said in an email to USA TODAY. "Similarly, in pictures from space we can plainly see a noticeably curved Earth."
In the 1988 report Derivation and Definition of a Linear Aircraft Model, one of the reports mentioned in the viral video, the authors write, “This report details the development of the linear model of a rigid aircraft of constant mass flying over a flat, non-rotating earth."
However, this is quickly followed by, "The systems have been broadly formulated to accommodate a wide variety of applications," and "These models are widely used, not only for computer applications but also for quick approximations."

Hank Pernicka, the director of Missouri Science and Technology's Space Systems Engineering Laboratory, said this is a common practice for aerospace engineers.
"It makes our modeling equations much easier to manage," he said in an email to USA TODAY.
Pernicka used the example of throwing a paper plane at one of his students.
"I really don’t need to account for the fact that the Earth is spherical, rotating and orbiting the Sun in order to throw the airplane accurately," he said. "For this short-range trajectory, those effects are quantifiable but trivially small."
Don Durston, an aerospace engineer at NASA's Ames Research Center, explained that Derivation and Definition of a Linear Aircraft Model is also focused on short-range trajectories and motions.
