Right, I'm saying that if it flew the Great Circle route on a flat Earth, the distance would be over 26,000 miles. On a round earth, the great circle distance is only 6300 miles, easily traveled in 14 hours.

Debunking the Flat Earth Azimuthal Equidistant Map Projection is much easier than it looks. This is the Real Azimuthal Equidistant Map Projection for spherical Earth: The Mean Radius of spherical Earth is 3 959 miles The Circumference of the Equator for 3 959 miles mean radius is 24 875 miles (Circumference Calculator) The Distance North Pole - Equator is approx 6 215 miles When we flatten a globe onto a 2 dimensional map, one thing must remain constant and that is the Circumference of the Equator. Therefore the Flat Earth Azimuthal Equidistant Map Projection would have the following inevitable errors: Since the Circumference of the Equator is a circle of approx 24 875 miles then the radius of that circle must be 3 959 miles. Difference between 6 215 miles (known distance North Pole - Equator) and 3 959 miles is 6 215 - 3 599 = 2 256 miles or 6 215 / 3 959 = 1.57. So we have 2 256 miles less or 1.57 times smaller distance value from the FE North Pole to the FE Equator. If flat earthers had to stick to the know distance of 6 215 miles, then: The FE Equatorial circumference would have to be 1.57 times larger than the known or 24 875 miles x 1.57 = 39 053 miles We know that the Equator divides the Earth in half and we know that a degree of latitude neat the Equator is approx 69.097 miles and diminishes near the poles. We also know that the Sun travels on the celestial sphere 15 degrees per hour which also means that it travels 1 degree every 4 minutes (60/15=4). Since 1 degree = 69.097 miles and 24 hours a day = 1 440 minutes: 15 degrees per hour x 69.097 miles = 1 036.455 miles, so 1 036.455 miles x 24 hours = 24 874.92 miles The Sun makes 360 degrees circle on both models of the Earth, so 360 degrees x 69.097 miles = 24 874.92 miles So the Sun movement at the Equator on the Celestial Sphere also indicates the Equatorial Circumference is approx 24 875 miles. Conclusion: The Flat Earth Azimuthal Equidistant Map Projection does Not properly represent parallels and compresses the shapes and sizes of landmasses North of the Equator and extends the shape and sizes of landmasses South of the Equator. When we look at the real Azimuthal Equidistant Map Projection, we are looking at spherical Earth form above the North Pole, therefore the circumference of the Equator is 24 875 miles, but since the surface of the Earth is curved, not flat, the distance North Pole - Equator is 6 215 miles, which is not a straight line in spherical geometry, but an arc of spherical Earth with mean radius of the sphere of 3 959 miles.

Even without using actual measurements, it's clear that the map cannot be correct: it is drawn with the "equator" at half the radius from the centre. So, calling the radius of the whole disc r, the area of the "northern hemisphere" is π x (r/2)^{2}, or (πr^{2})/4. The area of the "southern hemisphere" is πr^{2} minus the area of the northern hemisphere, or πr^{2} - (πr^{2})/4, which equals (3πr^{2})/4. In other words, the southern hemisphere is three times the size of the northern hemisphere on this map.

Also different circumferences for the FE Sun to traverse throughout the year indicate: The FE Sun has different velocities in order to maintain the 24h daily cycle. Circling slower at the northern hemisphere and faster at the southern hemisphere. The FE Sun changes angular diameter, i.e. Shape Shifting Sun. When it's in the northern hemisphere it has smaller angular diameter and when it's in the southern hemisphere it has larger angular diameter.

In addition to that flight, and the one that broke its record 30 years later, detailed here, there is also Elgen Long, who was the first to fly around the world over both poles, in 1971: Also: Calin Rosetti and Richard Norton in 1987; Dick Smith and Giles Kershaw in 1988/89; Bill Harrelson in 2015; and Miguel Gordillo in 2016.

I am amused by the irony in trying to use science & scientific arguments to convince a flat-earther, whose only motivation to believe the flat-earth is to prove that science is wrong.
