@GADAUNEWS To answer your first question, you can't. The Sun is never visible directly overhead from any part of the UK, nor from the southernmost point of South Africa. The highest the Sun ever gets in mainland England is 26.5 degrees below the zenith, at noon on the first day of summer, June 21, seen from Lizard Point. At the same time, the Sun will be about 58.5 degrees below the zenith, that is only 31.5 degrees above the horizon, seen from the southernmost point of South Africa. So your question is based on incorrect premises.
Your second question is simple: frames of reference. The helicopter, just like you and me, the air, and everything else, is moving along with the rotating Earth. You don't fly to the back of the plane at 500 mph when you leave your seat, do you? The helicopter lands on the same spot after hovering for the same reason.

@xxx.118 You are right about two things. Yes, we are lied to all the time. And yes, most people believe the Earth is round or flat or whatever because someone told them so- their parents, their schools, their friends, social media. Most kids don't get to experience hands-on how to determine the shape of the Earth for themselves, and it's a pity, because it's very easy to show that the Earth cannot be flat.
There are many ways of doing it, but the easiest is to build an equatorial sundial. This will prove that the Sun moves a constant 15 degrees per hour across the sky, at all times of day or year, from anywhere on Earth. This would not be possible on a flat Earth with a nearby Sun, because the Sun would move faster across the sky at midday when it's close than when it's near the horizon and thus much further away.
No electromagnetism, sonoluminescence, atmospheric lensing, or NASA necessary. Just working eyes and brain.
