Tom Cruise is attempting his most impossible stunt yet, this time up above the desertscapes of Abu Dhabi. For the latest installment of his Mission Impossible franchise, Fallout, the 55-year-old Hollywood actor is performing what is known as a high-altitude, low opening (or HALO) jump from a plane moving at a speed of approximately 265 km per hour and hovering around 20,000 feet above the earth. The stunt — the risks from which include hypoxia and the bends — is something that no other actor has ever attempted before and took Cruise over a year of practice to nail, according to the Independent.

Not challenging enough for you? “We have to shoot as close to sunset as we can, so we only get three minutes every day to get the shot,” one member of the film crew said (watch, runtime 2:37).
