After reading this thread I got my Classic Civil Airliners Guide from 1920-1964 out. Suprisingly there is not a section on the Caravelle but there is a section on the Vickers Viscount V.708 and oddly it features the Air France version. F-BGNK was, in fact, the first Viscount to be built and the first to be exported. It first flew on 11th March 1953 and delivered on18th May.
Unfortunately it crashed fatally during a crew training flight on 12th December 1956 near Paris killing the five Air France crew.
