What interested me the most was how Jake improved upon the late Joe Locicero's DTM (with a significant nudge from Bob Hoover) using hands-on, real-world testing of countless configurations of internal vanes. No sit-on-yer-butt computer benchracing, but real-world make and break and remake proofing.Readers of the technical and mathematical persuasion might be interested in knowing that another genius of the 20th century, the late Domina Jalbert, was an 'uneducated' innumerate and worked by the very same hands-on technique for decades and came up with the first revolutionary invention in air lifting research in thousands of years: the Jalbert Parafoil (Parasail) which he patented around 1964. His work is relevant to the topic and is a heartening example for the rest of us. Build, don't Bullshit.
