The Mercure was designed as a competitor to the Boeing 737-100 and 200 series. It first flew in 1971 and served with Air Inter, almost entirely within France due to a very poor range. This example is preserved at Speyer
Paris Air Show 1975 Saturday, prototype 02 became the most interesting Mercure. To satisfy Air Inters requirement for an eleventh plane in 1983 ,8 years after production ended, Dassault lengthened 02 to model 100 standard and it entered service in 1985
Just 10 of this French design were built, this one entering service in 10.74, although Dassault hoped to produce 300 by 1979 as competitors to the 737 and DC-9. Wfu at Montpellier in 11.94 and used by ESMA as an instructional airframe, painted in the bright colours of Air Littoral
This was the second prototype of the Mercure which featured at the 1975 Paris Airshow. Whilst it carries a full Air Inter livery I believe that it was still in the development stages with Avions Marcel Dassault at the time of this photograph.
