This is the near-death moment a Dubai police officer fell backwards into the spinning blades of a hoverbike that he was testing to be used as a first responder aircraft.

Shocking footage shows the bumpy test ride ending with a life threatening crash landing as the officer from United Arab Emirates city's law enforcement was tipped backwards into the propellers before rolling to safety.

Police had been test driving the Hoversurf Scorpion S3, painted in their white and green livery, as part of an initiative to use the hoverbikes for patrols and responding to emergencies across Dubai.

The video, first uploaded by the hoverbikes' manufacturer, California-based Hoversurf, has since been taken down, with Dubai Police attempting to remove every trace of the video from the internet, reports The Drive.

In the footage the pilot of the Scorpion can be seen ascending without issue. It is when he reaches his maximum altitude of 98ft that the aircraft begins to buck as if the flight controller is unable to tell which way is horizontal.

On the descent, the hoverbike continues to tilt and buck forward and backward until the rear of the aircraft makes contact with the ground.

The 253lb quad-copter then flips over onto the pilot with blades still spinning, resulting in a near fatal crash.

Hoversurf, who gifted the first batch of Hoversurfs to Dubai police for them to test in 2017, said the crash was due to a mechanical failure.
