Scanned from a 35mm slide at the NASA HQ some years ago. The basic shape here (FDL-7/McDonnell Model 176) appeared on a great many McD designs for the latter half of the sixties from small one-man experimental designs on up to full Shuttle-sized craft like this one. It had both sharply swept fixed wings on the bottom and stowable high aspect ratio wings for landing up top.
