Cool footage has emerged of the largest upright formation sky dive ever undertaken, performed in the skies above Arizona, USA.

​The video, captured using a GoPro, shows 52 skydivers flying together in an upright formation.

​Writing online about his group's achievements, the filmer said "When my buddies and I started trying to build Upright formations in 2012, when we set the Texas state Record (13), New Jersey state record (16) and the first ever US Nation record (16) we were told that building Upright formations much bigger than that would be near impossible."

"Flying upright is one of the most difficult positions to balance in skydiving. It is amazing to see that just in the last couple of years, the talent has grown enough to make these dreams possible. At this camp we set 3 World Records with a 44 person formation, and 2 back to back 52 person formations. Such a pleasure to be a part of the Feet First Revolution."

Although the footage was captured last year, it has only recently emerged online.

This is my view, Zachary R Sabel from the largest Upright formation the world has ever seen. This video is unedited and was shot using a GoPro Hero2 mounted on my head. This jump was our 3rd World Record in 2 days.
