A bit of artwork from Bell, circa first half of the 1960's. Depicts an SST vaguely along the lines of the B-70, with dropped wingtips for compression lift, but with 8 turbojets. The turbojets could tilt up to provide vertical thrust. No further data... may well *not* have been a fully serious design.
