Whats your point?  

 

It is fairly self-explanatory.

1. Drop Over Distance

A common approximation is:

• Over 1 mile (1.61 km), the Earth's surface drops about 8 inches (20 cm).
• Over 10 miles (16.1 km), the drop is about 66.7 feet (20.3 m).
• Over 100 miles (161 km), the drop is about 6,667 feet (2,032 m).

 

Thanks Mike.

 

@BillyBid, any additional insights?

Is it not possible that a round circle can be flat ? But if the earth is flat what does the "underside" look like?

I am wondering if it would be like someone sitting naked on a glass table ? All revealing like?

Not really.  There are direct flights between Perth and Johannesburg that go over the ocean and nowhere near Dubai..  Why did you post this???  Did you think there weren't flights?  Seriously, I really don't understand.

Research it and you will see the overwhelming majority of airlines do not offer direct flights, South African Airlines being pretty much the only exception.

Would you like a specific calculation for a given distance?

 

Sure, give me the calculation for 99% of the radius.  Say 6300km to make it a nice easy round number for you.  What would the drop be for that value?  

 

On a sphere that would very obviously be nearly the same as the radius, but using your formula I get a value of many thousands of times larger than that.

Qantas also flies it.  What a surprise that the only two airlines that fly between south Africa and Australia are Qantas and South African.....

Please do not make a very basic error in sense and mistake basic economics for the earths 'shape' as the reason certain routes are taken.

A very astute remark indeed.

A possibly valid remark.

 

If this were the only example given, I would agree on its limited relevance. I believe, however, that when there is a body of circumstancial evidence, then it warrants closer observation.

 

There are plenty of examples, I will look into them a bit later.
