Similar to the 200-inch mirror in the Hale Telescope, David Haymond's Concept 3 project took 11 years to build. Again, like the 200-inch mirror, he needed to take a nearly four-year break from construction, but finished with a concentrated four-year run of daily activity. David estimates he has 15,000 hours in the Concept 3. Stunning good looks have a habit of standing up to time, and the Mach III underscores the point. Dating from the Fox Mustang era, the Concept 3's lines are still mistaken for the next-generation Mustang or Ford sports car every time David takes it out. People can't believe it's a '92 design, with a school bus driver yelling down to him, "That's an '08, right?"
