This isn’t a scene from the next superhero movie. A store in London, England, is selling a real-life flying suit, a lot like the one Iron Man wears. It has five tiny jet engines—two on each sleeve and one on the back. A person wearing it can fly at about 32 miles per hour and can soar more than 10,000 feet in the air. The jet pack has enough fuel to run for about four minutes. But not everyone will get to fly like a superhero. Only nine suits are available—and each costs about $450,000!
