Here's the way I listed N-309. -SP

N-309, NASA V/STOL jet operations research airplane created from a modified North American T-39A Sabreliner with eight-to-ten General Electric YJ85-GE-19 turbojet engines - eight lifting engines plus two lift-cruise engines (composite lift hovering mode), or, ten lifting engines plus two cruise engines (direct lift hovering mode); not proceeded with.
