History

The Arc-en-Ciel completed several celebrated South Atlantic crossings between France and South America, operated by the pioneering aviator Jean Mermoz of Aéropostale. Its sleek low-wing design and three powerful engines gave it the range for overwater flights that were considered extremely hazardous at the time. The aircraft became famous for pushing the boundaries of long-distance aviation.

Variants

The Couzinet 70 was preceded by the Couzinet 10 and followed by the Couzinet 71 and 300 series, each improving on range and payload.
