If the Earth is flat - how it’s possible:

You can make the following flights, starting at 9am, finishing at 3pm (or earlier) and staying at the hotel till the next day:

• London, Uk => New York => Los Angeles => Tokyo => Doha => London, UK

• The above series of trips starts and ends in the same place.

• All the time, while flying, you’ve got the Sun on the left hand side.

You can only explain that in 2 ways:

• Earth is a globe as we know it, or

• Earth is flat, but then it needs to have a shape of a donut where the sun is in the center of it, so you fly around it.

The second would mean: when you fly South of London you should cross the middle of a donut (which is the Sun) after 12 hours of trip.

Let’s fly towards the sun:

London, UK => South Africa => the Sun.

Unfortunately, after 12 hours you end up in an extremely cold area.
