I have the same issues...the ghost weapon and after "say hello to devil" the game continues, you can fire up some grunts but after some SECONDS a cutscene will apear showing a AA soldier getting down your Black Hawk, so, being saved from the crash, you and the co-pilot survive but before you can do ANYTHING, another cutscene appears showing you a burned BlackHowk falling from the skyes directly to yours, so yo get smashed by it and guess what...you are death and the mission failed...no mather how far you run from the crash site....
Damn Bohemia and ArmA.
