As of January 2010[update], NASA achieved the first flight of a one-third scale, hover-capable Puffin technology demonstrator by March 2010 as the first eVTOL (electric Vertical Takeoff and Landing) aircraft concept. The concept was developed by Mark Moore, with several publications providing details of the design analysis and logic. By mid-summer 2010, they hoped to "begin investigating how well it transitions from cruise to hover flight".[2] As of August 2010[update], the one-third scale model of the Puffin was briefly on display at the NASA Langley campus for the filming of the Discovery network series Dean of Invention.
