Dassault Falcon 10/100
The baby jet of Dassault is a smaller version of the Falcon 20 with different cockpit windows and three or four cabin windows on each side. It also has a single nose wheel and a split passenger door, partly opening up and partly down. Apart from the Falcon 20 you could mistake it for an Aérospatiale Corvette.
Falcon 10 & Falcon 10MER
The first version was the Falcon 10. It is characterised by the three cabin windows on the right side of the fuselage.
Falcon 10MER is the French navy version of the aircraft, used for transport and communication.
A fourth cabin window on righthand right side of fuselage is the main difference with the Falcon 10. Other improvements include an increased takeoff weight, a larger luggage compartment and a glass cockpit.
