Gravity actually bends space itself which is how the Universe managed to smile at us.

Please tell me you aren't THAT stupid!
Let's use 3 miles. What is 32? 9
Curve Drop= 8"(9) = 72" = 6'
Three miles, not squared, is still just 3 miles.

Now I understand the application of what you said.
Thanks.
Not all of us are aviators or have been in Airforce.
Pretty sure it is a joke, but the flat earthers are real too. We had one here on the FR being very active. Always very polite, but mad as a hatter.
Correct. A flat map is a false representation, literally called a “projection”, of the earth. The earth is actually a globe. If you took a globe map of the earth and stretched a string between these two points it would be a straight line.
It just happens to be that 8" per mile squared is a good approximation using small distances.
It's a good approximation for ANY distance.
| 1 mile | 0.00013 miles = 0.67 feet |
| 2 miles | 0.00051 miles = 2.67 feet |
| 5 miles | 0.00316 miles = 16.67 feet |
| 10 miles | 0.01263 miles = 66.69 feet |
| 20 miles | 0.05052 miles = 266.75 feet |
| 50 miles | 0.31575 miles = 1667.17 feet |
| 100 miles | 1.26296 miles = 6668.41 feet |
| 200 miles | 5.05102 miles = 26669.37 feet |
| 500 miles | 31.5336 miles = 166497.53 feet |
| 1000 miles | 125.632 miles = 663337.65 feet |
Yeah, on rare occasions I have spoken with a flat earther. It’s a cult. The “1931” was a nice touch.
Always dress warm for those North Pole crossing!
that was hysterical, thanks for the morning laugh!!! :)
Is the horizon at eye level?
Drive out to the beach and look out at the horizon.
Is the horizon at eye level?
How is that possible on a sphere?
Do you EVER look DOWN to the horizon or does the horizon ALWAYS rise to eye level no matter the height?
Line of sight of the "observer", parallel to the ground and perpendicular at 90, not downward.
Do you see what is wrong with that image?
It’s best not to ‘think’ about it, but, rather, ‘do’ something. Next time you’re near a globe, take a piece of string, and stretch it between New York and Singapore. You will actually see the route.
Great circle route is shortest distance between two points on a ball. If memory serves me right
They fly great circle routes. The author of this article, and the TikTok folks, are blithering idiots.
Of course, if you are just using your GPS chart plotter, as most are, this is an automatic function. 
A linear aircraft model for a rigid aircraft of constant mass flying over a flat, nonrotating earth is derived and defined. The derivation makes no assumptions of reference trajectory or vehicle symmetry. The linear system equations are derived and evaluated along a general trajectory and include both aircraft dynamics and observation variables.

I don’t go anywhere anymore that would make my origin and destination look anything other than flat. The earth might as well be, since it won’t affect my navigation.
It is due to the Gulf Stream. I’ve been flying back and forth for years to Japan and it makes little difference if the destination/point of origin is LAX, SFO, SEA, ORD, MSP . . . they all follow the Aleutians over the Pacific.
I sailed solo from Panama to Hawaii to Guam in the late 1990s.
Interesting factoid: on the Panama-Hawaii voyage, when you are directly south of San Diego, you are already halfway to Hawaii.
How do you expect to make it the world’s longest flight if you fly in a straight line?
