Puff, puff, Puffin and away!!!
NASA is developing an aerial vehicle that will probably come as close to the personal jet-pack we were looking forward to. The “Puffin” features Vertical Takeoff and Landing, an electric engine, and a face-melting top speed of 300 miles per hour. They are already fine tuning its performance values for military use:
The rather unusual-looking craft would be especially handy for military applications. Its extremely low heat signature would make it difficult to detect in the air, and the fact that it’s whisper quiet doesn’t hurt, either. (Video)
In fact, because it’s so quiet similar technology may be used for commercial transportation in the future. The lack of loud, emissions-heavy aircraft engines would mean that airports could be situated closer to city centers and even residential areas. And if we can’t have personal jet packs, then personal aircraft would be the next best thing.
