World’s Longest Urban Zipline

A few adrenaline junkies have pushed the limits on adventure travel by creating their own urban zipline off one of Panama City's tallest buildings.

Attached to the 800-foot tall White Tower skyscraper, a rope stretched 2,000 feet across the city. But these adventures didn't make it all the way across -- they jumped off halfway for an added adrenaline rush of free-falling and parachuting to the ground.

The idea came from cinematographer Devin Graham, widely known as 'DevinSuperTramp' on social media sites. With only seven seconds between the skyscraper and the ground, zipliners have exactly four seconds before they had to let go and fall back to the earth below.
