From his post:
I am a student pilot. I've got 100 hours and 300 landings.

Throw a paper airplane. Does it fly in a straight line? Of course not. Neither does a big plane.

It only follows the course, horizontally and vertically, that the pilot controls it to fly. The way it turns from one heading to another is by temporarily banking to one side, exactly like a bicycle. The way it changes altitude above the ground is by using more or less power. The way it changes speed is by using more or less elevator trim.

All of these things are monitored by the pilot and adjusted as needed. If they are not adjusted, the plane flies at a constant speed, on a constant heading, at a constant rate of climb or descent above the earth.

Take a flying lesson. It doesn't cost much and is a great experience.

if i walk in a straight line, shouldn't i just start walking on air if i don't correct my course?

wtf kind of argument is that?

the question at its basis is wrong, because as you gain altitude, air density diminish, and doesnt produce enough lift and too much drag and you start falling, but lets say you have an airplane that nullify this problem, with an engine that works without air and can nullify gravity pull from earth, maybe yes you could, but no such plane existaccording to main stream media.

well, i mean, if you have thrusters, you can probably do it, that's essentially what rockets do (with a slightly different path)

rockets don't just fly straight up

maybe, im no rocket scientist.

will not argument about rockets, I know nothing.

good habit

yep yep

but the thing is, we don't need to go into complicated things when the model crashes at basic things like seasons, day/night cycles, triangles, etc..

the model failed at ancient greek time, dinosaur probably knew the earth wasnt flat

but I still dont know if @rivenator12113 supported, can you fall of flat earth, how thick is the crust, does flat earth revolve around the sun or the other way around, what is on the other face of flat earth? another flat earth ? can you stand on the other side of flat earth or you fall? and so on...

dinos were tall af, so they for sure saw the curvature of the earth :P

@Akhanyatin when u walk on land, is it the same as an airplane walking on some sort of support?

Not to mention just viewing polaris from different latitudes...

this guy using a bike, two sticks and a camera proove earth isnt flat yet he`s here arguing its flat... https://www.youtube.com/watch?v=YaPa4esJJx4

@rivenator12113 do you understand how an airplane flies?

@skywalk i don't know, but i don't believe in globe earth. polaris star wouldn't work on a globe earth revolving around a sun

@Akhanyatin what is the support that makes it magically keep altitude?

when we walk on earth, we have the ground, what does the airplane that makes them keep altitude when flying straight?

globe is the only way polaris works....

Each latitude would be viewing polaris at a different angle on flat earth - THAT is not what we observe.

this magical support is called air

air is keeping the plane on the same altitude?

aerodynamic lift keeps the airplane in the air

thrust generates lift on the right surface... like a wing

is taht yo flat earth @rivenator12113 https://qph.fs.quoracdn.net/main-qimg-cbab3189bcc4086f620034b7d2a1cc6a.webp

no because then the plane would be able to just chill at a certain spot without actually moving

i don't know @skywalk

then what are you arguing for if you can define what you support

you have to take a stance somewhere, so I know what im dealing with

i'm refuting your argument, you are sure of globe earth. i'm not sure what the earth is.

no lol @skywalk

You have done zero refuting...

Just 'nuh uh" so far

^

i can refute an argument without having an opposite stance

he`s just no flat earther he just want to troll people

again: you have done 0 refuting

just open your mind a little bit please. stop thinking earth is globe because nasa said so

open your mind a little bit please, stop saying nonsense because you want to feel special
