Sud Aviation Super-Caravelle
The Sud Aviation Super-Caravelle was an early design for a supersonic transport. Unlike most competing designs which envisioned larger trans-Atlantic aircraft and led to the likes of the Boeing 2707, the Super-Caravelle was a much smaller, shorter range design intended to replace Sud Aviation's earlier and successful Caravelle.
