This is the moment the Crown Prince of Dubai rushes into the sea to help a pal after a scary jetpack accident.

Sheikh Hamdan bin Mohammed bin Rashid Al Maktoum, 38, helped his friend, skydiver and thrill seeker Nasser Al Neyadi, after he zipped across the water surface in an aquatic jetpack and disappeared beneath the waves in the heavy gear.

Al Neyadi was attempting to hover 30 feet above the water when he propelled himself horizontally across the surface and then spent several worrying seconds under the water.

The Crown Prince of Dubai, whose nickname is ‘Fazza’, meaning someone who rushes to help another, waded into the sea to help his friend when things turned scary.

In the footage, Al Neyadi is seen strapped into the jetpack as a man apparently gives him his final instructions.

The adventure enthusiast seems to struggle with the weight of the equipment before suddenly propelling himself sideways.

Friends watching from the shore laugh, but suddenly stop short when Al Neyadi disappears beneath the waves in his heavy equipment.

With the engine still on and churning up the water, apparently keeping the wearer under the surface, onlookers run into the sea, including the Crown Prince in a light blue T-shirt.

However, Al Neyadi apparently manages to cut the engine and lift his head above the wave as friends approach him.

Al Neyadi confirms that he is okay and Fazza, looking relieved, leans in for a cuddle.

Instagram user ‘D.eyana.b’ commented: “Dear Lord, thank God for his safety.”

Netizen ‘3003.775’ said: “Thanks to God he is alright.”
