Top maps and Elevations maps place the center of the Panama Canal at 85' above both oceans and not at 301"
And that is irrelevant!
Why don't you prove you're not defeated. Verify the surface curvature of any landmass or Canal. You can do it!
It is very easy to verify the surface curvature of the sea from a ship at sea. Just ask a QMC. You can do it.😁
Here is a suggestion for you to prove that the earth is flat. You can do it. 😁
(1) Buy or rent a good camera with a good lens.
(2) Buy or rent a good telescope or telescopic lens for the camera of very high power.
(3) Buy an infrared filter and some infrared film for the camera.
(4) Go to the coast. Any place on Earth will do. A clear sunny day would be best.
(5) Take some pictures of one place taken from one place.
(6) For example a picture of the coast of Africa taken from the coast of South America will do.
(7) My own suggestion would be to go to Point Loma in San Diego and take some pictures of Diamond Head in Honolulu.
( 8 ) Post those pictures on this website. They certainly would prove there is no curvature of the earth and the earth is flat.
All of that equipment should be available at your local camera store and might not cost too much if you just rented it for just an hour or so.
Don't make it too hard for the poor guy. I doubt that an infrared camera could photograph that far.
But there are plenty of flat-earth videos (with good evidence for the Globe) showing a few hundred kilometres from aircraft.
Just ask for a photo of Alice Town, Bimini, the westernmost island of the Bahamas from Miami. It's only 83 km and should be easy to see if the earth is flat.
He could even climb the 250 m Panorama Tower in Miami if he needs to though that should be unnecessary if the earth is flat.
He should take a good level and see if the horizon really does rise to "eye-level" from that 250 m above MSL and not about 0.5° below.
Thanks, Rabinoz.
Maybe a better suggestion would be take pictures of Cuba from that " Southernmost Point In The U.S " marker at Key West, Florida.
It is only about 90 miles from there to Cuba.
Been there, but I couldn't see Cuba with my binoculars .
Must have been too much Haze in the Atmoplane that day ?
I have also been to the top of Point Loma many times but have never been able to see Diamond Head from there.
Farthest I could see was to the horizon and that was only estimated to be about 25 miles.
The top of Point Loma is about 400 feet above sea level.
On those ships on which I sailed we never could see Diamond Head or Point Loma until we got near to Honolulu or San Diego.
An old QMC said it was because of the curvature of the earth.
The reason I keep mentioning QMC's is that our Company Commander in Boot Camp was was a QMC with over 20 years service.
We were very much impressed with him. He never raised his voice, never '' chewed anyone out '' and must have had the patience of Job to deal with our bunch of '' Boots ''. If you goofed up he would just take you aside , explain to you where you erred, and explain to you what you needed to do.
