I haven't noticed any tall enough to work accurately in the middle of the desert or the Pacific, where GPS is used.
Earth is flat. Prove me wrong.

They circumnavigated around THE FLAT EARTH.
Lots of studies about it exists:

Natural causality is built for factual scientific observation.Can you show us one anomaly that contradict natural causality itself.

i notice references to plane flights taking diversions , Earth is not only home to mankind , several of Earths citizens migrate by flight , perhaps , the folly of human aviation ie map rading is not how we should look at this
do bird migration paths take the wrong turning of the roundabout like human planes is my question

No, those people believing in this comic-figure called trump are even worse

there is also the issue of alignments to stellar objects found in much of our ancestors holy places , i doubt that the flat earth can get these alignments , newgrange is a very good example , just north of Dublin , a burial cjhamber that at only one time in the year allows a shaft of sunlight to illuminate its deepest chamber ,
i think flat earth tries too hard to squueze everything to fit into its thinking yet it would struggle to justify the accuracy of heavenly viewing and marking in or on the land our ancestors excelled in
i cannot accept flat earth as anything other than a fallacy , but at least i tried to view it sensibly and not just deride it
its upto you if you want to obsess over this i think its a harmless obsession , so go for it

Earth is flat, people. Make your research.

President Trump Tells Boy Scouts of America Delegation that The Earth is Flat
1 DAY AGOby R. HOBBUS J.D.WASHINGTON, D.C. – President Donald J. Trump told a delegation from the Boy Scouts of America on Tuesday that he has “strong evidence” the earth is flat. “I’ve spoken to many, many experts, whom I won’t name, and they tell me the earth is absolutely flat,” President Trump told the delegation – which included an eleven year-old Cub Scout – during a meeting in the Oval Office.
A White House aide who witnessed the Oval Office outburst told Real News Right Now that Mr. Trump became agitated after two Boy Scouts – aged eleven and thirteen – presented him with an antique desktop globe bearing the Boy Scouts of America logo. “His face went from orange to red in a matter of seconds,” said the aide, who agreed to speak to the press on condition of anonymity. “The president asked the Scouts if they believed the earth was round and then demanded they explain why its curve isn’t visible along the horizon.”
On Friday, White House Press Secretary Sean Spicer backed up President Trump’s claim that the earth is flat, telling reporters in the White House Briefing Room that strong evidence exists in support of the flat earth theory. “I think that there’s no question that the earth is flat,” said Spicer in response to a question from The Washington Post. “The question is, is it disc shaped or a plane? I personally believe there’s been enough reporting on the subject to strongly suggest the earth is disc shaped,” said Spicer, who serves on the advisory board of The Flat Earth Society.
White House counselor Kellyanne Conway echoed Mr. Spicer during an appearance on Fox News Friday morning. “This is the President of the United States we’re talking about,” said Ms. Conway, who appeared on Fox & Friends wearing an elegant off-white dress from Ivanka Trump’s Spring Collection. “He has information and intelligence that the rest of us do not. If he says the earth is flat, then we the people should take him at his word.”
The BSA delegation traveled to Washington this week to submit their 2016 Report to the Nation to the president, a tradition that dates back to Franklin D. Roosevelt. The annual report summarizes the Scouts’ yearly accomplishments and goals for the future. President Trump, who was barred from joining the Boy Scouts as a youth due to “bone spurs” in his heels, called the report “tremendous,” saying, “They should give merit badges for this kind of thing.”

want to threat me? Not going to happen!
Sorry I don't have time to watch those. Could you explain it please?
Ok, GPS is a made to tell your location, isnt it?
It can be done with TRIANGULATION.
tHEN, "sattellites in outer space" are not necessary, specially because they dont exist.
The triangulation can be done with the antennas - there are thousands, maybe millions of them, around the flat Earth.
