Would you like to see a Royal Marine in a jet pack fly off a little boat and land on a huge ship like Iron Man? Of course you would.

Just like that, like nbd. He made it look so easy.

From the YouTube description:

The Gravity #JetSuit​ uses over 1000bhp of Jet Engine power combined with natural human balance to deliver the most intense and enthralling spectacle, often likened to the real life Ironman.

1000 horsepower! So stinking cool.
