For those wondering; The Specialised Downloads hosted by M4T will not install Mods. No aircraft, no planes, sounds, no whatever. They only make use of mods that are already installed, or you install later. Just see them as an "extra" to the mods. It is up to the user to install any mod if need be. There is a description (readme) file that will tell where to get them or support for them.
It's not possible for M4T to keep track of all mods or to give technical support for them. There are other sites that are specialized in that and doing a good job at it.
So: Downloads from M4T will not "mod" your game should you have a "standard" game.
