The Harrier jump jet flown by the U.S. Marines and the British Royal Navy
This was a mod made originally by rsvnpilot, and modified to be STOL here: http://www.lockonfiles.com/topic/38969-flyable-harrier-stol/
but this was a long while ago and I has been broken. But not anymore!
Maverick263 has fixed it, and It now works again! It uses the Su-25T cockpit, so everyone can use it!
slightly strange installation though, you have to put it in your default dcs folder (in my case "C:\Program Files\Eagle Dynamics\DCS World\Mods\aircraft"). then, in the aircraft folder, make a folder called "AI Flyables" (without the quotes), then put the "harrier" file in there.
that's it! Have fun flying.
I DID NOT MAKE THIS MOD!! I am just uploading it so that way other people can have fun with it.
