More about Jim Black and BlackBird Designs The Wright Brothers were bicycle mechanics who invented an airplane that took flight. I admire their innovation and creativity. I am also inspired by inventors like Gardner Martin who designed the EZ-1 recumbent bicycle. Different modes of transporation and vehicles of all sorts have always fascinated me. I am a pilot, aeronautical engineer, and inventor who designs and builds airplanes, ultralights, and bicycles for two. The Quadribent™ is one of my patented inventions that makes it possible for people to enjoy biking together. Almost anyone can go biking with the Quadribent. Below are pictures of a few other modes of transporation.

	SR-71 Blackbird My favorite airplane is The Blackbird, a Lockheed Mach 3 spy plane. Pictured here in front of the Air and Space Museum, San Diego, California.

	My Redwing Blackbird This is one of my other projects, a one-person home-built ultra light aircraft. I call it the Redwing Blackbird because I painted the top of the wings with red enamel paint for U/V surface protection.
