Adam Savage (Mythbusters) and personal jetpack flight
Adam gets a chance to test out a real to life flying backpack system produced by a civilian company called GRAVITY..
Later Adam contacted the Colorado School of Mines (Golden, CO) to have them build a titanium/polyurethane "Iron Man" suit. They used the original designs from the Movie and converted them to 3D printer compatible files, and the 3D Lab at the CSoM build it :)
Here is a short 10 minute movie showing the experiences -

1000 horsepower it appears is what is needed for reliable human flight without wings..
