“Adrenalin junkies Vitaliy Raskalov, 20, and Vadim Makhorov, 24, captured the dizzying bird's eye view from the top of the Shanghai Tower after a two-hour ascent. The pair, from Novosibirsk and Moscow filmed themselves breaking into and climbing the 2,073ft tower – twice the height of London's Shard building. Apparently unsatisfied with the view, they then climbed the crane on top of the partially-constructed building in Shanghai's Luijiazui district.

Unbelievably, the self-styled “sky walkers” used no safety equipment on their ascent and had to wait for the cover of darkness to avoid the Chinese authorities. Mr Makhorov said, "there are a lot of guards and cameras around in the day time, so we started climbing during the night, it was easier to stay unnoticed that way. It took about two hours to get to the top, but when we got there we could only see clouds. We were not afraid at all and we have never had any injuries as a result of our sky walking. As a result of our “mission”, we didn't get any sleep for over 24 hours, it was physically and mentally challenging for the both of us. Our target was to climb the highest tower in China and the seconds highest in the world, it felt amazing to accomplish it, the sky is the limit”!

In just one month in 2013, the duo conquered 12 cities in seven countries, scaling famous landmarks including the Eiffel Tower, and Barcelona's Sagrada Familia cathedral”. – Caters News Agency
