Did you watch the whole video? He said at the end that from a cosmic stand point the earth is practically a perfect sphere or something of that nature.
I'll give it another listen and get back to you. However, I've watched that interview so many times and have never heard it.

They don't because their sensors don't register this,
How do you know they don't register this though? Where are you pulling these absolutes from?
the pilots never tilt the noses of their planes as they fly, they change altitude but not orthogonality.
Yes, they absolutely do. When they are dramatically gaining or losing altitude, they pitch the plane respectively to gain or lose altitude quickly. If you've ever been on a plane before, you've felt when you're approaching the airport the pilot tilts the nose down and rolls slightly to lose altitude faster.

It still uses a convex lense, when a lense correcter is used the images are completely flat. Let me remind you I never said the earth was flat but no man that isn't affiliated with the organisations I mentioned can independently prove it is round either.
But how do you know it's a convex lens?


Oh I know you never said the earth is flat. What about SpaceX who has been to low earth orbit? Private companies like these plan on sending people into orbit.

How about having faith in mathematics, trigonometry and astronomical observation?
Mathematics is used to describe not explain, mathematics can only give answers to things people believe is true, you can't use mathematics to prove anything only lab experiments can do that.

Trigonometry is what allowed people to ask the 6.6 foot drop per mile question

That's not what I am talking about, obviously the plane must change angle to land, slow down or speed up. But while in cruise mode it should constantly be tilting its nose down to account for the earth's curvature. If it didn't then the plane would be on course to leave the earth.

But how do you know it's a convex lens?
All camera's that posses zoom features have convex lenses and some posses concave lenses. These types of lenses refract light and distort images. Lense corrector software always makes the images flat.

Well then if regular people like me and assuming you can go to orbit and prove it then I'll be ok with that.

Didn't get a chance to yet, my fault.

Or, the plane is simply maintaining altitude? When you fly you maintain altitude while not ascending or descending. It's not like the pilots sit there and kick back while the plane flies completely straight. Also, where are you getting the idea that no one has measured the curvature of the earth while flying(If that's what you're trying to say by all of this)?

Interesting, I'll take your word for it because I don't care to do any research on camera lens.

You can. Just pay money to. You can even go up to 34,000 Ft. and experience micro-gravity. It's only $5,000.

Mathematical calculations and observation of the angles of the shadow of then sun allowed ancient people to calculate Earth's radius almost accurately using just a couple of sticks. Not everyone believed in flat earth even back then.

Airplanes constantly need to fix their altitude from the sea level. Gravity takes care of the rest. I am not sure why you think the airplanes would need to make a nose dive per mile while flying at an average speed of 475–500 knots (878–926 km/h) when keeping with altitude works for them. Besides your question is based on the assumption that airplanes fly in a straight line (following a straight line on a chart paper) when they actually fly in a curve along with following the designated safe routes for them.

On a spherical surface, the shortest distance between two points is not a straight line, as it would appear on a flat chart, but a . Then comes the .

When I was in 6th grade when my father gifted me a math puzzle book published in Russia- among many trick questions it had, one was something like this- If a helicopter from Leningrad first flies 500 miles to north then turns west, flies 500 miles, makes anther turn to south and flies 500 miles and then turn east and flies 500 miles back where it would land- on a chart paper it should be back in Leningrad but in reality it ended up miles away because of the curved surface of the earth- it mentioned some lake in the answer where the helicopter would end up landing. I hope I got the question right and not messed up- I was 10-11 year at the time. The practical problem in not keeping Earth's curve in mind.. the further you go towards the north more prominent it would be as you travel from east to west faster. May be you should take a flight of that kind near equators and check out yourself.

This is quite humorous. I'm actually a pilot by profession, so I can provide answers to your questions/confusions:

-every plane flies within the earth's atmosphere, which is held to the earth by the force of gravity. A plane cannot 'leave' the earth as the gravitational pull or weight of the aircraft prevents it from doing so.

-a plane flies by producing 'lift' which is simply the reaction of high speed air flowing over its wings. If it were put into space, it won't be able to fly anymore as there is no air

- The force produced by an a/c's engines or thrust force is dependant on air and cannot function w/o it. Look up 'turbo fan' engines(the kind used by passenger planes) for details.

- There is a 'horizon' that every pilot(and most people) are familiar with. This is the line where the earth and the sky appear to meet. Such a horizon would not exist on anything other than a curved earth since, on say a flat earth you could see the peaks of mount everest from thousands of miles away.

Well said. Small note: although the shortest distance between 2 points is indeed a 'great circle' as you say, planes usually fly a rhumb line track as that cuts the meridians at a constant angle so the plane doesn't have to keep on changing it's heading.
