F-ZJRO was used as a demonstrator in French air force markings

The unique Falcon 30 demonstrator appearing at the 1974 SBAC show. In the mid sixties, Dassualt had plans to scale up the Mystère 20 design to carry 32 - 40 passengers and Eastern Airlines even expressed an interest in buying between 20 and 40 examples. The project was abandoned in 1975 thanks to high engine noise and the oil crisis, but the airframe is preserved at Bordeaux-Merignac

The mock-up of the Falcon 50 seen at the 1975 Paris Airshow.

This Super Mirage is a part of the Musee de l'Air et de l'Espace. It was the sole example built, a development of the Mirage 2000

The twin-engined Mirage 4000 was a big fighter in the F-15 class. No air force took a serious interest, but Dassault built and flew this prototype as a private venture.
