When the jet pack took its first flight in the 1960s, it was loud, difficult to pilot, and could stay in the air for about 30 seconds. Over 50 years later, not much has changed. But visionary engineers are hard at work to make them quieter, safer, and more practical. Will they succeed? See how new approaches with simpler mechanics may allow us to use these futuristic flying machines in ways no one has yet to imagine. Then witness pilot Nick Macomber's attempt to take a jet pack to world record heights, and hopefully make it back down!
