The writing is well done and I appreciate the added insights on the personal side, but as an engineer there are certain parts of the story that simply have to be told to really appreciate what they did. He does touch on some of it but are we not owed: 1. an explanation of their discovering the basic errors in atmospheric density at sea level. 2. the setup of the wind tunnels that allowed them to show most aerodynamic data was incorrect. 3. the explanation as they arrived at it of the interaction between roll and yaw and pitch in turning an aircraft. 4. the mathematics involved in the first derivation of how a propeller works. 5. a contrast between the first three and last fourth of the first flights. The point is these guys did things that are worthy of Noble prizes and risked their lives in the process and succeeded at minimum costs, and the author touches on that well when he describes C. Taylor's feelings he was watching them risk their lives on every flight at Hoffman Prairie, but you can't really appreciate why that is necessary without a deeper grounding in the technical as well as the human side. I am not saying doing an explanation would be easy I am just trying to show how without it the story is simply not grounded in the wondrous accomplishments that make it so wondrous. Their discovery is in every airline flying today and that needs to be shown not simply celebrated.
Again I appreciate the personal side but the hard work of explanation of how and why so important is missing.
