"On 29 April 1995, the last two Mercures in service flew their last commercial flight. The Mercures ran in total 360,000 flight hours, carrying 44 million passengers in 440,000 flights with no accidents, and a 98% in-service reliability."
From wiki…
Dassault was a really great manufacturer from the caravelle to the mercure they were kick ass in domestic aircrafts, Why isn’t available on the game?
the answer is hidden somewhere in your own quote
Well i believe that there are a few aircrafts available on the game that made there last flight back in the time when animals could talk so???Please give me an answer that i can take…
And that was their last commercial flights but not their last flights. Besides that was the Dassault mercure not the dassault caravelle for example or the brand new falcon…
Take a look:

or take a look here…
PRETTY COOL and sorry but just that image inside the plane with it’s range…that’s something… NOT totally stupid my sugestion i believe…
That was the answer - there isn’t any Mercure flying around in the world!
As we stated before, there will be historic server starting this year too - and I can tell you, that Caravelle and Mercure will be part of this too 
Yes that will be cool… But i got wrong in one thing. I thought that the caravelle was a Dassault aviation aircraft but it was made by Sud Aviation not dassault. Dassault had the breguet and the mercure and now the falcon.
"Taking old planes away just reduces the gameplay"....how? You are asking the AS team to do far more research in they're freetime on quite frankly useless features. There are far more useful uses of time than researching these aircraft which dont fly anymore. Are we really getting to a point where 300x Concordes are available just because it would be cool?
The majority of the users on AS like it because of its attempts to be realistic. Introducing an aircraft type that does not, and will not operate in a gameworld based on the now period is only going to drive people away. The idea for a historic gameworld has been discussed elsewhere and thats probably the place for this...
