Nice chart, I was in the top deck of the Tokyo Skytree just a few days ago. I don’t think a flag big enough to be seen from the ground could practically be mounted on something so tall.
Just came across this.

Visible from a considerable distance, the flagpole is located on Acuity’s campus along Interstate 43 between Milwaukee and Green Bay.
The flagpole is nearly 100 feet taller than the Statue of Liberty.
At 70 by 140 feet, the flag is the world’s tallest symbol of freedom.
Flags are taken down at the first sign of wear, such as tearing along the seams. A professional seamstress uses an industrial-grade sewing machine kept at Acuity to make repairs.
The 9,800-square-foot flag weighs 250 pounds.
