I was fairly impressed with the first episode of Savage Builds, which is now airing on the Discovery Channel. It's basically a show that lets Adam Savage (from MythBusters) do whatever he wants. In this case, he attempts to build an actual real-life Iron Man suit. SPOILER ALERT: He mostly succeeds. This is accomplished by printing out Iron Man armor pieces in titanium and then adding the jet suit from Gravity Industries on top of that. Yes, there is a real-life flying suit. It uses multiple small jet engines to provide enough thrust for a human to fly. Here is my previous analysis that looks at the power required for flight. (You can watch the episode for free, at least for now.)

But could a normal human being fly this thing? Maybe. Just maybe. Adam gave it a try and started to learn how to fly this jet-powered suit, but he wasn't ready to fly it with the added difficulty of wearing titanium Iron Man armor. Instead Richard Browning (founder of Gravity Industries) was the Iron Man pilot. The visual effect of seeing an actual flying Iron Man was epic.
