WALKTHROUGH VIDEO COMING SOON
Franklin goes over to Michael's to look for him but he isn’t there. Franklin then calls Michael who explains he is at Trevor's trailer in hiding with him and Patricia Madrazo. Michael tells Franklin briefly about the situation.
Ron is there and Trevor asks him how Trevor Philip’s Enterprises is doing. Ron tells Trevor about a Merryweather plane full of weapons that could be an opportunity for them. Trevor is keen and heads out of the trailer with Ron, telling Michael to stay behind with Patricia as he is a wanted man.
Get in the plane
Franklin calls Michael, and gets told that they are hiding out at Trevor's trailer in Sandy Shores. Following the cutscene, get in the truck with Ron and drive to the airfield, and get in the plane located in the hanger.
Fly to the cargo plane
Taxi the plane out of the hanger and take off. Fly to the cargo plane, ensuring you fly low to avoid detection by the military. When you near the Fort Zancudo military base, ensure that Trevor doesn't fly over it.
Proceed to tail the cargo plane until it gets to the other side of Mount Chilliad, when Ron will advise that it's safe to acsend and approach.
Fly close to the rear of the cargo plane
When Ron gives the all clear, ascend and approach the cargo plane. As you approach, the back ramp will open, and a Merryweather guard will fire upon Trevor with an RPG. Dodge if necessary, and continue approaching.
Fly inside the cargo plane
Fly directly into the back of the plane with the Crop Duster.
Take out the guards
Take cover and take out the guards, avoiding any incoming obstacles and working your way to the pilot's cabin. Climb the ladder, kill the pilot, and take the controls.
Fly the cargo plane back to McKenzie Field
Fly towards the McKenzie Airfield. On the way there, a couple of military jets will give chase, and eventually fire on the cargo plane, shooting out its engine.
Jump from the plane
With the cargo plane incapacitated, the only thing to do now is jump out of it. Run out the back (or get in the Mesa and drive out if gold is your aim).
Parachute to safety
Land safely to complete the mission.
Trevor will call Ron regarding the crashed plane, suggesting that the hardware could be recovered with dive gear, as well as to inform Trevor that the FIB are at his meth lab.
O'Neil will call Trevor promising revenge for the destruction of his farm and the killing of his brothers.
Accuracy - Finish with a shooting accuracy of at least 80 percent.
Four Wheel Filler - Exit the cargo plane in the Mesa.
