A North American Aviation artists impression of a supersonic transport derived closely from the B-70 Mach 3 bomber. An article on this concept by Dennis R. Jenkins was published in Aerospace Projects Review issue V2N1.

    Hmm, the “flow streamers” implying great speed, yet the wingtips not cranked down in their compression-lift position.

      Notice that the wings *don’t* have the fold-down hinges. Hard to fold the wings down without them; this might indicate that this version was *not* to rely on compression lift. By deleting that capability, a fair amount of weight, cost and operational complexity would be saved; the USAF might be cool with flying extremely expensive aircraft, but airlines need to be more cost-conscious.

        Starboard wing, about 2/3’s out. Sure looks like a hinge line to me and it passes through the elevon.

          Hinge *line,* but no hinge mechanism. Based purely on the art – which can of course be quite inaccurate – it looks to me like a B-70 that has been stripped and rebuilt as an SST, with the hinges removed.

          The B-70 wing hinge was a pretty big thing.

            OK, OK, it’s art. I see the line and assume the hinge.

            For those that could have seen it, seeing the wingtip drop 65 degrees would have required another Scotch or three.

    Tis beautiful, thanks for sharing.

    I have the Lindberg kit in TWA livery; it makes quite a conversation piece.

    And…na, judging by the city lights below it looks like it’s in climb-out on full reheat just after takeoff.
    The streamers look like normal condensation trails as you climb through a region
    of high vapor pressure (clouds in background).

    ‘Course as long as one is splitting hairs…you wouldn’t get far with most of the XB70’s fuel tanks taken up by the passenger cabin.
