When you stand by the coast of The Hague, you cannot see any part of England. England is about 170km away from The Hague. It would be impossible to see England anywhere you are in The Hague. The Hague’s outermost coast is about 170km away from England’s outermost coast. Plus, let us factor in the earth’s circumference of 40.000km. It is impossible to see England from The Hague, considering the distance. One has to be at a very high place to do this. A person has to stand at the height of over 2km at the edge of the coast in The Hague to see England. Plus, it would have to be in perfect conditions. At this point, this is impossible. There are no high structures at the coast of The Hague that are as tall as 2km. Also, it would be nearly impossible for perfect weather conditions to happen. No matter which angle you take it, the answer will always be the same. There may be theoretical and technical answers. No matter where you are on the coast of The Hague, you cannot see England. The only possibility you can see two countries at the same time is if you fly. Flying over the channel may possibly give you a glimpse of both places at the same time.
