This job is not for the faint-hearted - or those suffering from airsickness.
Three girls defy gravity on a regular basis by performing incredible stunts on the wings of a plane thousands of feet in the air.
The British based Breitling Wingwalkers, Sarah Tanner, Danielle Hughes and Stella Guilding, perform death-defying stunts while strapped to the wings of a plane as it loops and rolls through the sky at 150mph.
It is the world's only aerobatic formation wing walking team.
The trio dance, perform handstands and hang upside-down for adoring crowds across the world.
Chief wing walker Sarah Tanner, 31, wanted to be a wing walker since she was a child.
She said: "I've always loved dancing and wing walking is like dancing in the sky, but it wasn't until I was 24 that I first joined."
Now a wing walker for seven years, she lives with her pilot boyfriend Richard, 35 in Cirencester.
Sarah explained how becoming a wing walker takes determination and training.
She said: "To be a wing walker you can't be taller than 5"4 or weigh more than around eight-and-a-half stone and you have to have a head for heights.
"The plane travels at around 150mph so you're battling a lot of pressure on the wings and need to build a lot of core strength at the gym.
"We perform a lot of manoeuvres as the plane loops and rolls in the sky. We climb out of the cockpit and onto the wings where we do handstands, lift our legs, hang upside down, wave at the crowd and basically just dance on the plane's wings.
"People are always amazed when I tell them what I do for a living. A lot of people think I'm joking at first but they're always really intrigued about my unusual job."
Fellow wing walker Danielle Hughes also saw a wing walker display at an early age and was determined to fulfill her ambition.
She said: "It can be difficult at times, particularly if we have to perform in the rain, the rain really stings, it feels like you're being pelted with hail and can really hurt.
"It's like the ultimate rollercoaster, it's such a thrill.
"We also do this move where one plane turns upside down above another and I reach down and hold hands with my team mate on the other plane.
"The first time I did that was one of the most memorable moments of my life, such a good feeling and one I'll never forget."
