We will admit that we are big fans of Iron Man. Not just the song by Black Sabbath, but also the movies and the whole idea of having a personal flying suit. Looks like we are one step closer to having it with this jet pack they British Royal Marines were trying out. In the video below, you can see a British Royal Marine flying his Gravity Jet Suit over the ocean, from one boat to another. The first attempt seems kinda of silly because all he does is flip a ladder over the rail for his buddies. They couldn't get someone on the ship to do that for him? We are kidding.
