Credits to @DerekSP for the original aircraft. The Dassault Mercure 100 was an aircraft developed by Dassault Aviation, a company renouned for their military aircraft and private jets. The Mercure 100 would go down to be one of the worst failures of French civil aviation. The reason for this failure was due to a limited range, shorter than the 737, developed by Boeing, and since it was targeted for the American market, a country that's gigantic in size compared to other countries in Europe, with a limited range, it didn't sell a lot (Only twelve models sold, with one being a prototype), and the only aircraft they sold to an airliner was Air Inter, which later merged with Air France.
