All amateur balloon, rocket, plane and drone footage show a completely flat horizon over 20+ miles high. Only NASA and other government “space agencies”

If Earth were a giant sphere tilted, wobbling and hurdling through infinite space then truly flat, consistently level surfaces would not exist here.

Correct. It isn't trully flat.Differences are hard to spot but are real.

Surveyors, engineers and architects are never required to factor the supposed curvature of the Earth into their projects.

Mostly wrong.,ask somebody who studied geodesy. In fact they are studying hyperbolic geometry too. Of course the difference is small, just 1 degree per 111,2 km so sometimes is easier is to not include this corrections in most cases. less than difference hair for a mile is not so big thing.

If the Earth were truly a sphere 25,000 miles in circumference, airplane pilots would have to constantly correct their altitudes downwards so as to not fly straight off into “outer space;” a pilot wishing to simply maintain their altitude at a typical cruising speed of 500 mph, would have to constantly dip their nose downwards and descend 2,777 feet (over half a mile) every minute!

Escape speed is much higher than 500 mph.

so as to not fly straight off into “outer space

why satellites and space fall to atmosphere after long time ? Flat-earthers are imbeciles not understanding basic physics. Centripetal force you fools.

If the Earth were truly constantly spinning Eastwards at over 1000mph, helicopters and hot-air balloons should be able to simply hover over the surface of the Earth and wait for their destinations to come to them!

Again prove flath-earthers not know physics. Helicopters and hot-air baloons are moving with atmosphere. However those idea of travelling wouldn't be so stupid if you would leave atmosphere and wait indeed.It is currently just not affordable only as achieving escape speed require much more fuel.

If “gravity” is credited with being a force strong enough to hold the world’s oceans, buildings, people and atmosphere stuck to the surface of a rapidly spinning ball, then it is impossible for “gravity” to also simultaneously be weak enough to allow little birds, bugs, and planes to take-off and travel freely unabated in any direction.

Learn the physics and do the math flat-earth imbeciles...

The Statue of Liberty in New York stands 326 feet above sea level and on a clear day can be seen as far as 60 miles away. If the Earth were a globe, that would put Lady Liberty at an impossible 2,074 feet below the horizon.

Again physic,physics,physics. Atmospheric refraction.

I don't fucking care to debunk whole those flat-earth idiocy,but it is really funny to point some of it.

Antarctica was too cold to fly over,

It isn't about cold,it is about earth magnetic field and space radiation what would interfere with navigation both in Antarctica and Arctica. https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRFrnWq3OBZM89w_IoiNIQ3lxRENBjvSNRgubfX5_4kWSV3ZNx9eVAV1tObxgnj3HHmAms&usqp=CAU Moreover: nowhere to land if something gets wrong.

Things about planes - they travel mostly over land. Traveling over see is not good - nowhere to land if something will fail.Most flights are done over land because of that. Or on routes where you can turn to land area and land on it.

Also - it is about money and infrastructure. For example: Why Santiago to Sidney not trough new Zealand ? https://www.nzherald.co.nz/business/south-american-airline-latam-pulls-back-from-new-zealand-as-it-overflies-auckland/VQELIDMAV6ZDCREJKJRGYNFH2U/

Planes have to be refuelled.

however, using their own math and “law,” it follows that the Earth is 87 times more massive and therefore the larger object should attract the smaller to it, and not the other way around.

Again no even basic understanding of physics. Both attract themselves,but are also rotating. Centrifugal force opposes here gravity.

But explaining something than somebody don't like to have explained has no sense... However it is good lolcontent and good prove how uneducated and not knowing basic physics are flat-earthers.
