Socata ST-10 Provence
The Socata ST-10 Diplomate was a French four-seat touring aircraft with a low wing, retractable landing gear, and unusually sleek lines for a piston single. It was developed from the earlier Rallye family but aimed at a faster private-travel market. Production was limited and the design was soon eclipsed by more established American aircraft. The ST-10 remains a rare example of France attempting to build a high-performance personal aircraft for export.

Sold at times as the Super Horizon 200 and the Provence before its final Diplomate name, it stretched the GY-80 Horizon's cabin and added power.
