Are there any pilots or ocean navigators who ascribe to this theory?

I certainly didn't say I touched it. I used my eyes to verify it. The possibility of him falsifying this is perhaps real, just as it is when you need to show identification to board an airplane or some other day to day activity. Other pilots have verified this, and those who disagreed either got angry and left, or eventually agreed that they were seeing what they expected to.

Well, it was obviously photoshopped.

I’m a pilot and I can tell you the maps I use will not work on a FE model. I’ve used these sectional maps for over 25 years. http://ww1.jeppesen.com/personal-solutions/aviation/vfr-charts.jsp
This was before GPS was even affordable for the average pilot. If you overlap two sectional maps they won’t line up perfectly. It’s because you can’t project a round object on to a flat surface without distortion.

Edit: Actually they are called charts not maps but I didn’t  know if everyone was familiar with the difference.

The same thing is true on oceanic charts . There are also charts covering such small areas of the oceans as to limit the amount of distortion when projecting a round object (the globe) on a flat surface (a chart).
If you have ever seen deck plans or  pictures of compartments or rooms on ship you will find those marked "Chart Rooms".
In them  you will find they may have many cabinets with many drawers containing many charts due to the smal areas covering small areas of the ocean.

I would have to review it to be sure I have the right scene in the right movie. LOL.
There is a scene in the (1953) movie "Titanic" in which Second Officer Charles Lightoller is shown  plotting the location of icebergs on such a chart, illustrating how a chart might be used.

I might comment that during my service in the U.S. Navy , the words "flat earth" were never heard or used.
If someone had said that they believed the earth was some kind of a flat disc surrounded by a wall of ice, they would have probably been put on Sick Leave and sent to the nearest Navy Hospital for a mental examination and then probably sent for training to a Navy School in map reading.

There are so many subjects such as charts and maps of which many people are unaware of their existence until someone explains them to them. But the flat earth notion seems to be that if you don't know something about something - like charts for example - you just deny that they exist or just say they are fakes when information is presented to the so-called "flat earth believers" by the so-called "round earthers" who just like to present facts and evidence that they know - not just that they "believe" but they know - to people who just might like to learn about them .

In proportion to the earth's population there are probably a lot more people that don't know the first thing about these aeronautic and oceanic charts  than those who know about them and how to use them in their daily usage in their jobx.

The point I'm trying to make is how would you know from looking at a pilots license whether it was real or not? Do you work for the aviation industry in any capacity? Would you know how to spot a fake?

There is a big difference between observation and verification.

And onto the apparent other pilots that you now say have verified this: Who were they? What credentials did they provide to prove they were pilots? Do you have any links to forum discussions about this? Or who these users/people were?

I would have thought that such a monumental staggering claim from a pilot about flat earth - along with the supposed verification of said pilots credentials - would have been meticulously documented by any serious flat earthers wanting to build a body of evidence?
