Seasoned BASE jumpers Omar Al Hegelan and Nasser Al Neyadi reached speeds of 220km/h as they plunged 672m in 90 seconds from Dubai’s newly opened Burj Khalifa tower, gulfnews.com reported.

Al Niyadi, who has completed 2700 jumps and holds a world record for the first ever Mt. Everest sky dive, described the feat as "the best experience ever".

"When we were at the top of the building I was thinking 'this is crazy'. I was a little nervous but I wanted to jump from the highest tower in the world to record an achievement for my family and for my country," he told gulfnews.com.

BASE jumping is a highly dangerous sport involving jumping from a fixed surface and free falling before deploying a parachute.
