I have been trying to desperately beat the Toreno's Last Flight mission, but for some reason I just can't. When ever I first start the mission Iget two stars for shooting those two police officers on the helicopter pad. The cops start to chase me and then when I get out of the car to shoot the helicopter they shoot me.Also one other thing that happens is I shoot the helicopter, and the blast from the explosion blows me back and I get wasted. I tried doing this mission about fifteen times. Someone pleez help me.
