Lennson Experimental has expired. ShadowFox Research has replaced it.

The SF-1X is ShadowFox's first foray into the market of small jets. With two engines, one above each wing the Altamaha, painted blue like its namesake river, has a top speed of 255 mph in a straight line. That may not sound like much, but this jet makes up for it with its extreme agility. Our best engineers spent countless hours poring over aerodynamical data, and this is the result.
