When you walk into Jetblue's Terminal 5 at JFK these days, you'll find a mini aviation museum slowing growing in their giant, open marketplace area. First, there was a giant jet engine on display, with an interactive display about airplanes and even a button you can push to make the engine spin. But their newest addition, to help celebrate Jetblue's tenth anniversary, reminds us of the days when we all thought we'd have jetpacks in the future; they're now exhibiting a bite-sized private jet with folding wings.
