Any early-McDonnell history experts out there?
The XP-67, about which I'm writing for Air & Space Smithsonian, was the first design actually built by the new McDonnell Aircraft Corp., first filght early in 1944. James McDonnell was an MIT-trained aeronautical engineer (and a pilot), and it would be nice to assume that he himself designed and engineered the surprisingly advanced blended-wing/body airplane. (It was a failure because of its dreadful engines, but that's another story.)
Does anybody know if McDonnell did design the XP-67, or did he by that time have a staff of competent engineers who did that sort of thing while he ran the company?
