You can now buy a real-life Iron Man suit—if you have Tony Stark money

Gravity Industries is selling a jet suit powered by five micro-jet engines, two on each arm and one on the back. It can fly as high as 12,000 feet at speeds of up to 32 miles per hour. But you’ll need Tony Stark money to buy it: the suit costs $443,000. And there’s another catch. The partially 3D printed suit can only fly for three to four minutes (slightly longer in the cold, because cold air is denser).
