could a private jet be based of an SR 71 blackbird. By this I mean similar styling and shape. Would this be a good basis to make a private jet super sonic (disregarding sonic boom). What would the major adjustments be for the SR 71 to be a private jet?
By this I mean: to make a cabin of decent size; take off and land at non military airports; standalone (not needing refuelling etc) and yet supersonic travel.
