Window wipe scenery of the world's tallest skyscraper "Burj Dubai"

The skyscraper "Burj Dubai" in the largest city of the United Arab Emirates "Dubai". Its height is about 818 meters, and it is still reigning as the tallest skyscraper in the world. Such Burj Dubai is also dirty, so it is necessary to clean regularly, there seems to be a movie shot of the fact that the trader is cleaning windows while being suspended from the outside.

When cleaning the windows of the building which boasts as high as this, it seems that they are not quite a fierce person, they seem to have gone out of the waist but conversely if this is high, the reality will disappear and it may be that work is going to be extraordinary unexpectedly.

Movie playback is from the following.

This is the tallest building in the world "Burj Dubai". The height is about 818 meters.


The airplane looks pretty close.


It is high enough to reach the airplane.


I found people doing window wiping.


When looking down, it seems that it will not be a place to work.


If you look closely you will see that it is pretty dirty.


By the way it is around here that I wipe the window.


How long will it take to complete the window wiping with a small number of buildings of this size?
