Forget the Segway. Leave that jet pack behind. NASA is working on a personal flying suit.

Conceptual designs for the experimental vehicle, called Puffin, were introduced by Mark D. Moore, an aerospace engineer at NASA’s Langley Research Center, at a meeting of the American Helicopter Society on Jan. 20 in San Francisco. The Puffin is designed to be 12 feet in length, with a total wingspan of 14 and a half feet; it would weigh in at 300 pounds (without a pilot).

Two major elements distinguish the Puffin suit from the jet packs of ’50s-era sci-fi flicks. First, it is completely self-contained: the pilot would actually step into the suit, which has a cockpit-like area and helicopter-style blades, allowing for high-altitude flying (unlike those sci-fi jet packs).
