9. Helipads for the U.S. military on Okinawa Island in Japan
We take a look at 10 of the most extreme helipads in the world. A helipad is the landing space only designated for helicopters to land and take off. They are usually visible with a green background and a large ‘H’ in the middle, so pilots can see the landing spot from up in the air. These extreme helipads range from the middle of a major city, to the edge of a cliff and even in the centre of a forest.
