What power settings did the full sized Sabre land at? The use of the word supersonic was intended to include transonic and just below sonic which is what airliners fly at. Besides that there is the particulars of the wing design and the aircraft design to consider. I have worked 40 years with a BS in Aerospaace Engineering and know that you can't apply speciific ideas to all aircraft in general. The "thin supersonic wing" concept is a fact and not a theory.
