Interesting! The "official" pics of the XF-91 did not show the radome,
which should boost inlet efficiency.


Maybe, Orval. But that little inlet probably speaks tons about
performance...

IIRC, the XF-91 was built just before aero engineers discovered the
advantages of shock attachment for supersonic flight. The flat inlet
causes a shock, which adversely affects performance.
